in some codepoints from the real thing, especially
0x5c: yen sign instead of backslash,
0x7e: overline instead of tilde.
We can't use the real SJIS since otherwise Win32
pathnames would become invalid. OTOH, if we return
"SJIS" here, then libiconv will do mb<->wc conversion
differently to our internal functions. Therefore we
return what we really implement, CP932. This is handled
fine by libiconv. */
