I still do not find the document of Microsoft on how to transcode 
characters invalid in Windows but valid in other systems (like `?`), but 
Wikipedia has a good reference on how to solve (on user side) the 
problem, using alternate characters:

https://en.wikipedia.org/wiki/Filename#Problematic_characters

The glottal stop ʔ (U+0294), the interrobang ‽ (U+203D), the inverted 
question mark ¿ (U+00BF), the double question mark ⁇ (U+2047), and the 
black question mark ornament❓(U+2753) are allowed in all filenames.

An in an other site I found the full width characters may be used.


In any case, please considere security implications on using any 
workaround (especially if file is shared).
