Description Jamie Zawinski 2002-10-31 05:46:01 EST
I tried to remote display grip from a fresh install of Red Hat 8.0 to a
box running Red Hat 7.3.  All text in all labels and text fields is
garbled: there is a square "box" character inserted between every real
character in labels and text fields.  So if it should say


instead it looks like


Someone suggested setenv GDK_USE_XFT 0; that did not help.

This happens in both 24 bit truecolor and 8 bit pseudocolor mode.

The machine on which the apps are running is a fresh install of Red Hat
8.0.  The machine on which the apps are *displaying* is a Red Hat
7.3+Ximian box, with XFree86-4.2.0-72.

$LANG on the RH 8 box is "en_US.UTF-8".

grep -i font ~/.gtkrc*

     no match

grep -i font /etc/gtk/gtkrc.utf8

     fontset = "-*-helvetica-medium-r-normal--*-120-*-*-p-*-*-*"

running xlsfonts -fn '-*-helvetica-medium-r-normal--*-120-*-*-p-*-*-*'
on the 8.0 box with $DISPLAY pointing at the 7.3 box:


Setting $LANG to C makes grip behave correctly.
Comment 1 Owen Taylor 2002-10-31 16:39:05 EST
Does it happen for all gtk1 apps or just grip?
Comment 2 Jamie Zawinski 2002-10-31 16:50:37 EST
Also happens for:


so I'm thinking "all programs using libgtk-1.2.so.0"
Comment 3 JLapham 2002-11-04 12:43:11 EST

Just a shot in the dark, but I wonder if this is somehow related to bug 76248
that I reported.  Im my case, changing from LANG=en_US.UTF-8 to LANG=en_US fixed
the problem.  You mention changing LANG to "C" fixed the problem for you, what
happens if you try en_US?



PS: yeah, these two problems are probably unrelated... I'm just hoping to stir
up *some* response on these bugs...
Comment 4 Owen Taylor 2003-01-14 23:27:11 EST
After setting up a test environment, finding a pure-Xlib test case,
spending a bunch of time tracing through Xlib, I suddenly remembered
a detailed analysis of this exact problem. Namely: 


By me, in fact.

It turns out that this is a Hard Problem. (Because Xlib i18n is screwed
up in ways that I can't describe in a family bugzilla report).

There is a simple change to the Xlib configuration files that will
make this problem go away. Edit /usr/lib/X11/locale/en_US.UTF-8/XLC_LOCALE
and move the fs0 entry to the end and renumber fs0 through fs6.

However, this ruins the nice property that if you have an iso10646-1 font,
and you specify


You are guaranteed to get your font and only your font. (iso10646 is
functionally equivalent to Unicode.)

It also will be noticeably less efficient in some cases.

That being said, I'm of the opinion that we should go ahead and make this
change, basically because X fonts are a legacy item at this point,
so we should favor:

 - Simplicity and reliability of getting something on the screen

As compared to:

 - Power of configuration
 - Efficiency
Comment 7 Mike A. Harris 2003-02-07 08:23:09 EST
The suggestion you're making is with an installed system file and not
from the source code.  The two differ as I've just had a peek at this.
Since you understand the problem much deeper than I do, please make
a patch to the X source code and attach it for inclusion, preferably
after testing it first to ensure it does what is expected.
Comment 8 Owen Taylor 2003-02-10 22:53:40 EST
I don't fully understand your comment. Yes, it's a data file change,
not a source code change; why is that relevant?
Comment 9 Mike A. Harris 2003-07-10 10:44:56 EDT
Because patching the source code is easiest if the patch was created
against the source code.  A lot of the data files included in XFree86
installation are modified versions which were produced through automatic
processes during X building, and a patch made against the installed system
versions wont apply to the source code version.

Rather than try to patch it, I prefer to get patches made from the source
code files to start with, which the person submitting the patch has actually
tested applying it to XFree86 sources.  It's less work on my end to do this

Alternatively send it upstream, and it can be pulled out of CVS once it is
