If the filenameismeant to be readable, yes, you won't be able to see the
difference. But if you want to display a precise file name that canbeused
for example as a program parameter or in an URL, the Unicode filename needs
to beesacped using some convention:
* The URL encoding convention will be useful for the web (or even locally in
"file:" URLs). The web now generally assumes that URLs should be encoded
* The shell escaping mechanism will be useful on Unix (need to escape
backslashes, quotes, controls...) ifyou want that this Unicode string fits
in a 8-bit "char" string in a command line.
* In command line parameters, the caller still can specify the encoding
usable to display meaningfully that escape-encoded binary parameter.
