I guess that this code should be changed to something like:
```c
if((unsigned)c < 256)
{
    if(locinfo->pctype[c] & _LEADBYTE)
        return c;
    return locinfo->pclmap[c];
}
```
but it needs more tests. Also a quick check shows that pctype is generated incorrectly for DBCS codepages - it needs to be fixed first.
