Hi, I think I ran into a bug working on a pure UTF-8 web site. Command
[::rivet::upload filename] calls internally
int TclWeb_UploadFilename(Tcl_Obj *filename, TclWebRequest *req)
{
Tcl_SetStringObj(filename,
TclWeb_StringToUtf(req->upload->filename,req), -1);
return TCL_OK;
}
which converts a UTF-8 encoded filename in a new UTF-8 string. The bug
hit hard at first because files having names with character such as 'à'
or 'è' etc. created calling [::rivet::upload save ...] look correct on
the file system but any attempt to manipulate it subsequently (copying
it, changing permissions..) using the same Tcl variable resulted in a
mere 'file not found' error. And there reason was that '::rivet::upload
save' copies the file with the original unconverted name thus concealing
the fact that the string returned by 'filename' was different. A
workaround is re-converting the filename from utf-8 before any file
manipulation, but it's an inconsistent behavior. Fixing it without
breaking existing software is hard, so I will try to figure it out but
unless I come up with a good solution, I would confine any code breaking
change to rivet 3.0
