PhpDig.net - CP 1250

I had small problem with pages using CP1250 and PHPDig. After while I found solution, which is not very nice, but works.

1. set iso-8859-2 in config.php
2. add to $phpdig_string_subst['iso-8859-2'] problematic characters čžť - sipmly C:ÇĆ change to C:ÇĆČ ...
3. ok it works, correctly add records to database, but it doesn't display problematic characters in searching page.
4. add header to search.php
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title><phpdig:title_message/></title>
<META http-equiv="Content-Type" content="text/html; charset=windows-1250">
<META http-equiv="Content-language" content="cs">

5. remove this part from template which you would like to use
6. That's it.

I hope that I will not disturb somebody with this solution. If anybody has better idea how to sort out CP1250, please post it.
