OK, here is some example code (it's from 'tickr' application code).

Thanks. This looks like a useful avenue to try out.
The wide char win32 is completely alien to me. Do you have some pointers
to get me started ? Especially some example code would help me a lot.
I'm running into the bad filename conversion in two ways:
1. Users can specify an override directory via the GNC_DOTGNUCASH_DIR
environment variable. I'm currently reading this via g_getenv, but it
returns the wrong result.
2. In the absence of the environment variable, the default path is being
created starting from the value of g_get_home_dir. This as well returns
the wrong result.
