Your test misses the actual issue: on mouseup local tStr local tFilter put "a*b" into tFilter put "anything bold" into tStr filter tStr with tFilter put tStr end mouseup
Will yield "anything bold" while using the following 2 lines: put "a?b" into tFilter put "a*b" into tStr will yield "a*b" Finally, using the following 2 lines: put "a[?]b" into tFilter put "a?b" into tStr will yield "a?b" The point is that you can end up with issues if you are counting on "*" and "?" to filter literally. They don't - they are wildcards and can match anything (multiple char or single char respectively). The "[" is also special. To ensure that your filters work properly if you do not want to use any wildcards (i.e. match * and ? literally) would require you to change *, ?, and [ to [*], [?], and [[].
