strange display of glyphs in a second window

strange display of glyphs in a second window

[François Patte]

Bonjour,


I am facing a problem if I open a new frame (C-x 5 2): some glyphs are
displayed as if emacs could not read them (a square with the code of the
glyph).

For instance & is displayed as: 00 in a red square.
                                26

Also in the bottom bar, the name of the open file is displayed in the
same manner.

I don't understand why... The first frame is OK!

How to correct this?

thank you.

Check out your default-frame-alist and initial-frame-alist, if you
customized them.  Or maybe you are invoking Emacs with a command-line
switch that specifies a font.  Either way, somehow you are forcing on
all frames but the initial one a font that doesn't have glyphs for
some characters, so Emacs displays them as boxes with the character's
codepoint.

I invoke emacs with command line: $ emacs

I have this in my .Xresources

Emacs*font: -adobe-courier-medium-r-normal--24-240-75-75-m-150-iso10646-1

But the problem remains if I delete it....

I did not custom any default-frame-alist or initial-frame-alist

Absolutely no problems for displaying glyphs in the initial frame.... I
also use indic unicode glyphs without any problems. Problems occur in
the second frame (invoked with C-x 5 2)

Yes, that's what I said.

What does "C-u C-x =" say in the second frame about the font used to
display the characters that are displayed correctly?

If I open the new frame with the same text in both frames, I get for the
same letter:

in the first frame
x:-adobe-courier-medium-r-normal--24-240-75-75-m-150-iso8859-1 (#x64)

in the second frame:
xft:-unknown-FreeMono-normal-normal-normal-*-24-*-*-*-m-0-iso10646-1 (#x45)


More strange: there is an interaction with latex commands; for instance,
{\bfseries some text} is "normal" in the first frame, while it is
displayed as a code point for each character (including spaces and line
feed (C-j)) in the second frame...

Italicized text {\itshape some text} is italicized in yellow color in
the first frame  (which the normal behaviour) while it is in upright
character underlined and yellow in the second frame...

I use Auctex; there might be some interaction between Auctex and Emacs....

Perhaps not related to your issue but if you see above what I am seeing:

I dont see

This may not be an emacs issue at all – just set your thunderbird to
use UTF-8 instead of latin-1.

However it may be an indication that your locale settings are not utf-8.
What does the following (at the shell) give? I get for example

$ echo $LANG
en_US.UTF-8

Ok so thats not the issue then. And I dont know what is.

In any case it might be worthwhile making sure of UTF-8 in thunderbird:

That's your problem: you need to find out why does Emacs try to use
that bad font for your frames.  It's some configuration issue on your
system.

If the problem happens in "emacs -Q", then it probably isn't related
to AUCTeX.

Could you try something like this in your .emacs:

(add-to-list 'default-frame-alist '(font . "-adobe-courier-medium-r-normal--24-240-75-75-m-150-iso8859-1"))

?

Trying to search for "FreeMono" in your Emacs config files (and
additional packages) might also give a hint.

Problem does not happen with -Q option.... So, I understand what you, it
is related to Auctex...

Thanks, this partially fix the problem: code points disappear, but some
differences remain in the second frame: text in command \textit{some
text} is underlined and not italicized (in emacs, TeX compilation is not
affected!)

I tried many grep commands and did not find any FreeMono....
