Cool! This may have changed recently, see this pronouncement from the
development team in January:
You tweeted using the web interface, which apparently worked, but it's
certainly the case that there are other Twitter clients that don't
know about UTF8 in particular, and (perhaps unnecessarily) truncate
after 140 =bytes=. Some SMS services (whence Twitter got it's 140-
whatever limit) transfer non-ASCII in UTF-16, so the limit there is 70
On a related note, there are also apparently some bugs in the way the
Twitter backend stores text, such that sometimes tweets get truncated
after the fact, as the data migrates deeper into their backing store:
You may want to check that tweet in a few days time to see if the
arrow is still there.
Isn't i18n fun?
