Re: [LINUX5250] xt5250, x5250, fonts (also Screen bleeding)

[Dave McKenzie <davemck@xxxxxxxxxxxxx>]

I've had the misalignment problem in xt5250 for many months, since
upgrading to SuSE Linux 9.1 (I'm currently on 9.2).

I finally found it's related to Unicode and UTF-8.  It looks like xterm
is interpreting some characters that translate to ASCII codes > x80 as
Unicode.

In SuSE 9.2 the LANG environment variable is "en_US.UTF-8".  It was
"en_US" in SuSE 9.0 (in which xt5250 worked OK).

So to turn off the UTF-8 mode, I put this line in xt5250:

LANG=en_US

and added LANG to the export statement.

That fixed the misalignment.  Also, it cleared up the "screen bleeding"
problem I was seeing.  It was most obvious when doing DSPPFM on a file
that had bytes that translate to ASCII codes > x80, such as in binary
and packed fields.  As you roll through the file, parts of the data
would be misaligned, and after rolling to the next screen, some
characters would remain where they had been on the previous screen.

But I haven't found how to fix the misalignment when using tn5250 in a
console.  I see there's a line

CONSOLE_ENCODING="UTF-8"

in /etc/sysconfig/console, so maybe fiddling with that will help.  Or
maybe some option in setfont.  But I guess that would affect all
consoles; maybe changes would have to be made in tn5250.  I don't use
tn5250 in a console so it's not a priority for me.
