BTextView character width is often incorrect for multi-byte characters

[axeld]

I haven't yet figured out how to reproduce it, but in Mail with character size 14 I have it quite often that once I use multi-byte characters (like äöüß), the width computation is incorrect, and the cursor is at a wrong position.

I think it could be reproduced by opening a text file which contains lots of multibyte characters, like those in the canna input addon. At least, I remember once I fixed a couple of problems there by using those as test case.

And, indeed, it's reproducible by opening /boot/system/data/Canna/default/fixer.canna for example.

#2334 could be related.

FWIW, I also see this sporadically when writing emails in Japanese. It does not happen all the time though, and I am not sure what triggers it.

I was unable to reproduce this in hrev38006 (with the file mentioned and my own tests).

Most probably this was fixed with hrev36304 - please reopen if you encounter the problem again.
