Here is someone who looked for non ASCII characters:  
[/t/12909/1](https://community.mp3tag.de/t/12909/1)

or this one by DetlevD: [Unicode to ASCII](https://community.mp3tag.de/t/7279/1)

Or you could compare if the filename matches the format string that you used when creating the filename:  
"$ifgreater($strstr($lower(%\_filename%),$lower(%title%)),0,1,0)" IS "0"  
(replace the %title% with the format string)
