Subject: describe-char says that DejaVu Sans Mono is being used to display a 
	raw character
Date: Mon, 23 Mar 2009 16:17:38 +0100

As a consequence of bug#2741, after vc-annotate I get a buffer that is
nominally utf-8-dos but contains raw bytes, for example:

ca005e53 test.txt (Juanma Barranquero 2008-01-29 08:56:38 +0000   32)
;;; Preparaci\363n

If I `describe-char' the \363 character, I get:

          character:   (4194291, #o17777763, #x3ffff3)
  preferred charset: eight-bit (Raw bytes 128-255)
         code point: 0xF3
             syntax: w 	which means: word
        buffer code: #xF3
          file code: not encodable by coding system utf-8-dos
            display: by this font (glyph code)
      uniscribe:-outline-DejaVu Sans
Mono-normal-normal-normal-mono-13-*-*-*-c-*-iso8859-1 (#x03)

  Character code properties: customize what to show

  There are text properties here:
    face                 vc-annotate-face-FF3F3F
    fontified            t

which seems wrong. In fact, I can only reproduce this at work; on my
laptop, with a very similar font setup (both have nearly identical
fonts, including the very same version of DejaVu Sans Mono)
`describe-char' says that it has no font available for that character.

The relevant part of the font log:

font for: (243 . iso-8859-1)

I can't reproduce that problem on GNU/Linux system.

This is very strange.  243 is the byte code of that raw-byte
character #x3ffff3.  But, usually the log should say that
the character code is #x3ffff3, And, it says that the
character has `charset' text property `iso-8859-1'.  But,
describe-char doesn't show that property.

Is it a Windows specific problem?

I suppose so.

Unfortunately, I've just lost access to the only computer where I was
able to reproduce the problem, so I think we should either close this
bug, or tag it as +moreinfo on the hope that it can be reproduced
(I'll try to duplicate on the laptop the font setup I had at work as
exactly as possible, but it's a long shot).

I still see #2741, though.

Oops, I should have respond in this thread much earlier, sorry.

I agree with +moreinfo.  How to do that?

> I still see #2741, though.

I have no knowledge about vc.el.  Isn't it possible to fix
this bug within vc*.el?  Does it require more fundamental
change?

No problem; it wasn't a serious bug anyway (not to mention being
almost non-reproducible).

> I agree with +moreinfo.  How to do that?

Just Cc: to control <at> debbugs.gnu.org, and start the message with

tags 2755 + moreinfo
quit

No, I think it's just vc.

FWIW, I can now reproduce #2755, so if you want me to try something, just ask.

I cannot reproduce it anymore, so I'm closing this one.
