Strange screen characters

Strange screen characters

[Hufnus]

Since I can not use
$_term_char_set = "ibm" anymore with dosemu 1.3.x

what do I need to use in $_internal_char_set so that
Norton disk editor can display the IBM high ASCII characters
correctly and the screen becomes readable?

Thanks
TonyB

The default settings ("cp437"="") should "just work". If it
doesn't then you should mention some more things so we can
fix the bug. In which terminal (xterm? console? konsole?)
are you running dosemu? What does "ldd `which dosemu.bin`"
tell you? Do you use UTF-8 or not?

I use cp866.

Its the same problem in all of them.

I do.

These Norton Utilities loads the custom
font, so they work 100% correctly only
under xdosemu with the DOS font. But
with the VGA fonts it is only a little
broken, at least I can read what's
written there in the menus. While under
the terminals - it is a complete garbage,
I can't even read the letters.

Strange. I tested today again with some Borland IDEs (just to get some
box characters) and it just works, can't reproduce your problem, at least
as long as I have 80 characters per line. Both with slang1-utf8
(Debian) and slang2.

Can you download slang 2.0.3 from www.s-lang.org and see how dosemu works
with that one? Just so we know where the problem is, RedHat or us?

But you should really check
Norton Utilities. Everything
else works, that's strange, yes.

It's been ages since I've even seen them, but I seem to recall that the Norton 
Utilities did "fancy" things with screen handling, like reprogram some of 
characters in the font (or something similar to that) to have rounded corners 
and other stuff.

If you're trying to run this on a linux console, you may need to set direct 
console and/or graphics modes.  I don't have a dosemu handy but I believe the 
settings are "$_console = (1)" and/or "$_graphics = (1)"

I hope this helps,
Pete C.

The difference is that Norton uses bright background colours
and the blink/acs hack was messed up somewhat.

Here's a quick patch, I'm working on something better but
I'd like to know if this helps you too.

Two mysteries remain:
Unpatched 1.3.2 works fine with Norton in two situations:
a) Linux console in utf8 mode (using unicode_start and a
utf8 locale)
b) Using slang 2.0 (this patch only affects #ifdefed code)

In all other scenarios it was messed up indeed.
But you seemed to imply otherwise.

I don't have CVS access at the moment, just a floppy (!).

Yes, I have the utf8 locale
and unicode_start, yet I had
problems. And your patch solved
it, thanks!

:)
Excellent chance to do the dosemu
hacking.
