Comment (by p_enrique):

 I have two more comments on this matter:

 1. I think there are plugins like cyr2lat, arabic-to-lat etc. that convert
 characters in Non-Latin scripts to ASCII. These will work if they hook to
 `sanitize_file_name`.

 2. There should be an extra filter for Windows-based servers that tries to
 convert everything possible to ASCII and strips out the rest. Otherwise,
 the attachments and images ''will'' break under Windows. But such a filter
 would need a fallback filename for a case where converting/stripping
 leaves no ASCII at all. What would that be?
