SA doesn't support UTF8 regex. It's just matching plain byte strings. Depends on normalize_charset setting too, for best compatibility you should match both latin and utf-8 raw byte variants: ΓΌ -> (?:\xfc|\xc3\xbc) https://cwiki.apache.org/confluence/display/SPAMASSASSIN/WritingRulesAdvanced Or check the replace_tags in 25_replace.cf, there's ready templates for characters (but they match some commonly obfuscated variants too).
