We are receiving a lot of spam with Cyrillic font. Spamfilter seems not to be able to scan such fonts, and not recognize cyrillic fonts in black list keywords

result: spam with cyrillic characters is not blocked.
 
Can you suggest a solution?
 
Thanks

rudaf,
 
If it is truly just a font, the message source itself has the text in it so I can not see how changing a font could prevent keywords from working.

Rudaf,
 
OK ... got it.  It is not so much a font but ACTUALLY Cyrillic letters. Not too sure on this.  Need to think.
