This appears to be based on the usedDefault return value of WideCharToMultiByte. I believe this is insufficient: WideCharToMultiByte might convert Unicode characters to codepage characters in a lossy way, without using the default character. For example, it converts U+0308 (combining diaeresis) to U+00A8 (diaeresis) (or something like that, I forgot the exact details). So if you have, say, "p-umlaut" (i.e. U+0070 U+0308), it converts it to U+0070 U+00A8 (in the local code page). Trying to use this as a filename later fails.
