@hdu: OOo internally keeps file URLs in UTF-8 and, when interfacing with
external entities, converts relevant data between osl_getThreadTextEncoding and
UTF-8. This is a very old design decision that directly impacts large bodies of
code. Of course, if the relevant data contains characters that cannot be
represented in osl_getThreadTextEncoding, this causes problems. This appears to
be a problem mainly on Windows (where the system uses UTF-16, i.e., full
Unicode, but osl_getThreadTextEncoding is always one of the legacy 8-bit
character encodings, each only covering a small subset of Unicode). However,
for Windows, a solution could be as follows:
Use the ...W instead of the ...A variants of relevant system calls (so that,
e.g., Asian characters in a user name are transported correctly regardless of
locale). Depending on surrounding code, either directly translate between the
Windows UTF-16 data and OOo's UTF-16--based rtl::OUString or, in a two-step
process, translate in one step between the Windows UTF-16 data and temporary
UTF-8 data and in another step between the temporary UTF-8 data and the OOo data
representation via a new osl_getThreadTextEncoding'. That
osl_getThreadTextEncoding' would be like osl_getThreadTextEncoding, but for
Windows would always return UTF-8 (all places that currently call
osl_getThreadTextEncoding would have to be checked whether or not they have to
be switched to osl_getThreadTextEncoding').
