Please test. I'll backport it to 6.2.x then.

Note: For mysterious Tcl (?) reasons I cannot set iso8859-1 and iso8859-2
but utf-8, iso8859-15, iso2210-jp, koi8-r, euc-jp etc work.
Maybe my installation...


I confirm. Same happens on my instalation. tcl/tk 8.4.12, Ubuntu Dapper
32bit.


So we are happy since most of the encodings now work.


Not having ISO-8859-1 working is a pretty major issue.


I am still not sure if it is a local problem or a general one or depends
on the tcltk version.


Can you provide more details, preferably including a recipe to
reproduce the issue using either spearfish or a new location?


Sure (eg Spearfish):
d.mon x0
v.digit -n newmap
# now go to "Settings" icon, "Table" tab, "Add column", add a column of
your choice, "Create table"
# close the "Settings" window
# digitize a line
# enter a value into the attribute popup form
# "submit button" (default is utf-8 which seems to work)
# change the encoding, click "submit button" again and voila' the error
appear in the terminal

Okay.

I'm pretty sure that the problem is that lib/form/form.c doesn't call
Tcl_Main(), so the library path doesn't get set, so Tcl can't find its
.enc files.

Realistically, if you are trying to use Tcl/Tk and your program
*doesn't* look very much like tkAppInit.c, all bets are off.

Rather than trying to process the data from the form library in C,
form.c should just register the commands then do the rest in Tcl.

Since I know nothing about tcl, I'll leave that to the experts. AFAIK
form.c was
originally written by Radim.
