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
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
