Find in Resources (Ctrl+F) does not work in Restorator 2005

Restorator 2005 build 1442
Input of a cyrillic font in dialogue Search (Menu Resources - > Find in Resources) incorrectly works.

Can you please give some more detail:

• is it impossible to enter cyrillic characters?
  • if yes, what else appears, nothing? or a wrong character?
• or you can enter cyrillics, but when pressing the search button
  • nothing happens
  • an error message appears
  • words are not found in spite of existing in the resources

Thanks for any other detail.

Florian
