Double byte problems, characters being cut short

[Reesy]

Hello,
Can anyone point me in the right direction?
(see screenshot attached).

The squares in the red circles are where a double byte character has been cut in half, ie its not displaying correctly.
Im guessing this is because the products short description is being set to an odd number, but I cant find where this is in the code.
Its in box the index listings, ie click a category, showing its contents, and also when you sort by manufacturer.

Any pointers here would be appreciated.

Not quite sure who moved this into this forum, it was a general question.
Its not a contribution, its part of a template, but anyway.

Which files are controlling the index listings, and manufacture listings please anyone?
