Thank you for that clarification Stephan. Yes I was referring to input limits
in microblogs. This is presented to the User as a Counter which starts at 140.
So however the characters are stored or transformed in the backend is of little
interest to the User. The User is interested in the Counter. So U+2026
decrements the Counter by 1 whereas U+002E U+002E U+002E decrements the Counter
by 3
There are (and in some cases have been) unexpected variations on this simple
User oriented Counter mechanism for microblogs
① Twitter - Until recently, characters outside the BMP resulted in a Counter
decrement of 2 and BMP characters gave a decrement of 1. Not sure when the
change happened but now both BMP & non BMP characters result in a decrement of 1
② Sina Weibo - The Weibo Counter has 3 possible decrement values : 0.5, 1 & 2.
• Characters from Unicode range U+0000➜U+00FF have a count of 0.5
• Characters from Unicode range U+0100➜U+FFFF have a count of 1
• Characters from Unicode range ≥ U+010000 have a count of 2
About a year ago I blogged about it
