Twitter Character Count

【Update: Do not know when it happened but Twitter no longer differentiates between BMP and non BMP characters WRT character count. All characters now have a count of 1. I may, at some stage, delete this article but, for the time being, I will leave it here as an historical record of the evolution of Twitter.

In a previous article I examined Sina Wēibó 新浪微博 character count for a user post schappo.blogspot.co.uk/2012/10/weibo-character-count.html Lets now examine twitter. The stated and generally understood limit is 140 characters for a tweet. This is not strictly true. The actual tweet limit is variable and ranges from 70 to 140, inclusive. Different characters have different counts, as follows:

  • Characters from Unicode range U+0000➜U+FFFF have a count of 1
  • Characters from Unicode range ≥ U+010000 have a count of 2
Or, to put it another way — Characters in the Basic Multilingual Plane (BMP) have a count of 1 and characters in the other planes have a count of 2. The 2 Mahjong Tile characters used in the example below are from the Supplementary Multilingual Plane (SMP).

Lets illustrate with a made-up posting that contains characters from the 2 Unicode ranges, above. The following text has a tweet character count of 17.
  • one two 一二三四五
  • 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 2 + 1 + 1 + 1 + 1 + 1 + 2 = 17

Weibo Character Count

Same as all the other microblog systems I have encountered, Sina Wēibó 新浪微博 has a 140 character limit for a user post. This is not strictly accurate. The character limit is variable and ranges from 70 to 280, inclusive. It depends on which characters are included. Different characters have different counts, as follows:
  1. Characters from Unicode range U+0000➜U+00FF have a count of 0.5
  2. Characters from Unicode range U+0100➜U+FFFF have a count of 1
  3. Characters from Unicode range ≥ U+010000 have a count of 2
Some of the consequences of these differing counts are:

  • If one writes in everyday English then one has up to 280 characters as these will be Latin characters in Unicode blocks Basic Latin and Latin-1 Supplement U+0000➜U+00FF. The Latin Script does though occur in several Unicode blocks en.wikipedia.org/wiki/Latin_characters_in_Unicode. Latin characters in Unicode blocks other than Basic Latin and Latin-1 Supplement will have counts of 1 or 2 and usage of them will reduce the 280 limit.
  • For a Chinese only post then if all the Chinese characters used are in the Unicode Basic Multilingual Plane (BMP) then the limit will be the accepted 140 characters. There are many Chinese characters outside of the BMP and because they have a count of 2, usage of these will reduce the 140 limit. The extreme case being a limit of 70 if all characters used are Chinese characters outside of the BMP.
  • In recent releases of OSX and iOS, Apple incorporated Emoji characters en.wikipedia.org/wiki/Emoji The majority of these Emoji characters are outside the BMP (ie ≥ U+010000) and so will have a count of 2.
Lets illustrate with a nonsensical posting that contains characters from the 3 Unicode ranges, above. The following text has a Weibo character count of 13.

  • one two 🀂一二三四五🀀
  • 0.5 + 0.5 + 0.5 + 0.5 + 0.5 + 0.5 + 0.5 + 0.5 + 2 + 1 + 1 + 1 + 1 + 1 + 2 = 13

My Adopted Chinese Name

In China there is a very famous Canadian by the name of Mark Rowswell dashan.com. One of the reasons he is so famous in China is that his Chinese is very very good. His adopted Chinese name is 大山 (dàshān) which means great or large mountain.

Several years ago I decided to also adopt a Chinese name. One day a name popped into my mind. Mark's Chinese is very good but my Chinese is only basic. Consequently, I chose the name 小山 (xiǎoshān) which means little mountain ☺

An advantage of having an adopted name is that one can change it and I can change it to reflect my progress in mastering the Chinese language. So as my Chinese improves I can change it to 中山 (zhōngshān) which means middle mountain. Then 大山 (dàshān) and finally, if I ever reach this level of proficiency, 巨山 (jùshān) which means gigantic mountain.

There are though, some days when I think my Chinese is so poor that maybe my adopted name should be 微山 (Wēishān) as this means micro mountain.

Language Characteristics

In this article I list some of the characteristics of natural languages and scripts as they are manifested and used in modern day IT. With languages there are always exceptions and so there will be some exceptions to these characteristics. I will not be delving into linguistic technicalities such as the distinction between mora and syllable or the distinction between logogram and ideogram. I will take a more broad brush approach.

Arabic

  1. Arabic is written in the Arabic script
  2. Written from right to left
  3. The space character (U+0020 SPACE) is used as a separator between words and sentences
  4. The sentence terminator full stop is the Unicode character U+002E FULL STOP
  5. Unicase ie no uppercase and lowercase letter forms
  6. A Keyboard Mapping is sufficient in order to write Arabic
  7. The Arabic script is inherently cursive and hence is presented/displayed in it's cursive form.
  8. Letters change shape according to their position within a word. These different shapes are named Initial, Medial, Final and Isolated forms. en.wikipedia.org/wiki/Arabic_alphabet#Letter_forms

Chinese

  1. Chinese is written in the Chinese script which consists of hànzì (汉字) characters, of which, there are tens of thousands
  2. Written from left to right. Once browsers implement CSS3 Writing Modes we may well see some return to the traditional vertical text in webpages dev.w3.org/csswg/css-writing-modes/#vertical-intro
  3. There is no space character separator between words and sentences
  4. The sentence terminator full stop is the Unicode character U+3002 IDEOGRAPHIC FULL STOP
  5. Unicase ie no uppercase and lowercase letter forms
  6. An Input Method is required in order to write Chinese
  7. All characters, including punctuation, are monospaced. Thus, for example, the list items separator in the text string "北京,南京,东京" is the single character U+FF0C FULLWIDTH COMMA. The text string "北京、南京、东京" uses the single character U+3001 IDEOGRAPHIC COMMA as the list items separator.
  8. With respect to number of characters required to communicate, Chinese is much more compact than English. Given a sentence written in English, the same sentence written in Chinese would require far fewer characters. This compactness gives Chinese a significant advantage over English for IDNs and when microblogging.

English

  1. English is written in the Latin script
  2. Written from left to right
  3. The space character (U+0020 SPACE) is used as a separator between words and sentences
  4. The sentence terminator full stop is the Unicode character U+002E FULL STOP
  5. Has uppercase and lowercase letter forms
  6. A Keyboard Mapping is sufficient in order to write English

Japanese

  1. Japanese is written in the Japanese scripts Kanji (漢字), Hiragana (ひらがな) and Katakana (カタカナ)
  2. Written from left to right. Once browsers implement CSS3 Writing Modes we may well see some return to the traditional vertical text in webpages dev.w3.org/csswg/css-writing-modes/#vertical-intro
  3. There is no space character separator between words and sentences
  4. The sentence terminator full stop is the Unicode character U+3002 IDEOGRAPHIC FULL STOP
  5. Unicase ie no uppercase and lowercase letter forms. Uppercase is sometimes used for emphasis in English. Similarly, Katakana is sometimes used for emphasis.
  6. An Input Method is required in order to write Japanese
  7. In general, Japanese, like Chinese is monospaced. The exception is that there are half-width forms of Katakana and some punctuation characters. The half-width forms are in Unicode block Half-width and Full-width Forms U+FF00 ➤ U+FFEF.
  8. With respect to number of characters required to communicate, Japanese is much more compact than English. Given a sentence written in English, the same sentence written in Japanese would require far fewer characters. This compactness gives Japanese a significant advantage over English for IDNs and when microblogging.

Korean

  1. Korean is written in the Hangeul (한글) script
  2. Written from left to right
  3. The space character (U+0020 SPACE) is used as a separator between words and sentences
  4. The sentence terminator full stop is the Unicode character U+002E FULL STOP
  5. Unicase ie no uppercase and lowercase letter forms
  6. An Input Method is required in order to write Korean
  7. The individual Korean letters (jamo/자모) are grouped into and displayed as Syllabic blocks. e.g. the individual jamo ㅎ ㅏ ㄴ ㄱ ㅜ ㄱ are combined to form the two Korean characters 한국

Russian

  1. Russian is written in the Cyrillic (Кириллица) script
  2. Written from left to right
  3. The space character (U+0020 SPACE) is used as a separator between words and sentences
  4. The sentence terminator full stop is the Unicode character U+002E FULL STOP
  5. Has uppercase and lowercase letter forms
  6. A Keyboard Mapping is sufficient in order to write Russian
