Did you set LANG variable to UTF-8 before starting eggdrop?
env LANG=en_EN.UTF-8

Actually Tcl is localized and is observing the LANG variable.

I think the problem is most likely fault of eggdrop, because eggdrop
still is using the old functions that aren't localized.
For eggdrop any string that goes through is interpreted as ascii
The problem with UTF is that is using multibyte encoding. So length of
the string cannot be calculated by counting the bytes of the string.

Most likely the problem is that tcl tells eggdrop that the string has
14 characters, but in UTF 14 characters doesn't mean 14 bytes. Since
eggdrop don't know UTF it cuts out 14 bytes.

As for the solution. The best thing would be to convert eggdrop to use
internationalized functions to process the text. This probably is a
really big task. There is probably easier solution by just fixing this
part of code where you have error, but I'm sure there are more places
that have similar issue.

Anyone interested in fixing this?
