Cyrillic not being displayed properly?

[AdolfinWolf]

I am trying to add the following as my personalized text,

Code:

Cayл - xopoший чeлoвeк

Which is being cut off to

Code:

 Cayл - xo&#108

This is the case with most words / sentences.

For example

Code:

пoбeдитeль

becomes

Code:

пoбeдит&

Is this an error/bug or what am i doing wrong? Is cyrillic not allowed?

Or does it simply take up the max amount of chars allowed in the personalized text, hence why it cuts off like that?
