Thanks Hin-Tak and Dan but I think we're at crossed purposes now. Remember that my original question had nothing to do with paths. I simply used paths as a convenient example. My question is about command-line parameters and (more specifically) about UTF-8 string conversion. Here's an example.... Consider a Windows user whose name is Göran. The UTF-8 byte sequence for this is:-
47 C3 B6 72 61 6E -- (6 bytes)
whereas Windows would expect something like this (depending on the user's locale):-
47 F6 72 61 6E -- (5 bytes)
Let's suppose that a Linux app launches a Windows child process (via Wine). The (Linux) host app needs to pass the string "Göran" as one of the command-line parameters. Linux uses UTF-8 and will therefore pass the first sequence of bytes to Wine (6 bytes). But Windows doesn't understand UTF-8. A Windows app would expect the second byte sequence (5 bytes - or 10 bytes for a Unicode app).
Does Wine carry out the necessary conversion or does it simply pass the original byte string unmodified? That's what I'm trying to find out. Thanks.
