This thread is giving me flashbacks to the times before Unicode, when swapping files between Windows and Linux partitions would have a good chance of fucking up every non-ASCII characters in their names.
There was ways to set it up so the ISO character sets would match, but it was still a giant pain to deal with different ones.
Blessed be Unicode.
A related issue I still see very often, even with files newly created just this year, is when trying to extract zip files on my Linux systems that contain non-ASCII filenames and that were created on Windows systems, especially ones with apparently non-English locales like Japanese. Need to trial and error the locale I give to unzip and sometimes hack together fixed names with iconv until the mojibake seems to fix itself.
