charset translation in xdosemu

charset translation in xdosemu

[ivan]

Hi,

I got dosemu working with character translation cp895->iso8859-2 and it
successfuly runs using utf8 xterm and luit -encoding iso-8859-2 dosemu .
But, it dos not work in xdosemu. Is translation not implemented for xdosemu?

Using dosemu-1.3.1 and following .dosemurc

$_X_font = "terminus-iso8859-2-24"
$_term_char_set = "ibm"
$_external_char_set = "iso8859-2"
$_internal_char_set = "cp895"

Well, it works with a cp895 font. I'm just being curious about the translation.

I also tried compiling plugin/translation and setting external_char_set to utf8
and run it without luit under utf8 xterm, but all I got was a screen full of
at-signs.

Also, would it be hard to implement iso-10646, so that xdosemu could use the
same font as the rest of apps in X? I know nothing about Xlib or fontconfig or
whatever it involves. I might leran though.

No, translation is not implemented for xdosemu display, except for
copy/paste.

The $_X_font in xdosemu must be a 1-1 DOS font (cpxxx)
Or, with $_X_font = "" you can load a DOS bitmap font just like in real
DOS.

Here $_term_char_set is superfluous (indeed in the CVS version it no
longer even exists; and $_external_charset defaults to the locale, so most
users will only need to decide on the internal charset).

That's to be expected, because support for utf8 terminals in only present
in the CVS code for the moment, and only if you use a utf8-patched slang
library or the recently released slang 2.0.

You may have a look here
http://www.inp.nsk.su/~bolkhov/files/fonts/univga/
I think there are some Xlib calls which print unicode characters directly.
The XDrawImageString call would need to have an alternative into a call to
convert cpxxx to unicode and feed that to XDrawImageString16 I think.
You're most welcome to have a go at it.
