I want to remove characters with Ascii codes 226, 128 and 142 from the file names.
They create a lot of trouble.
A display in UTF-8 from SAS creates the following garbage characters.
29 %put # &kw1;
�
30 %put # &kw2;
�
31 %put # &kw3;
�
I tried to create removal rules in Mp3Tag using Alt+Ascii codes, and thought it might work, but apparently (probably) they weren't removed.

Hum, I just noticed these are multibyte characters from UTF-8, so maybe that's why it's not working.
Here's a screenshot of the characters I need to remove (in yellow):
