 Their explanation is attached below along with your original report.

I wonder why this bug was closed. I didn't see any change related
to it in the changelog of the new version. And I can still see the
effect of this bug in fvwm 2.5.27.ds-2.

 I think your diagnosis is wrong. You are seeing the symptoms,
  and there are bugs open:
  * #452661 [i|  |  ] [fvwm] Titlebar can not show all characters

This is not the same bug. In bug 452661, the correct title seems to
be shown, but there's apparently a font problem.

  * #488224 [n|  |  ] [fvwm] Window titles are incorrectly displayed if
 fvwm is running in utf-8 locale

Probably a different bug, as in my case, FVWM running under the UTF-8
locale is OK. In fact, the testcase provided is this bug just shows
an encoding-related bug here (but the correct title is displayed);
same problem with zsh (when displaying the zsh prompt in the titlebar)
BTW.

Note that in my case, the problem occurs under non-UTF-8 locales. And
this is *not* a font or encoding problem: a completely *unrelated*
title is displayed by FVWM. More precisely, when I do tab switching
under Firefox, the title is not updated when the new title contains
a character that is not in FVWM's charmap.

This is a much more important problem than the other two, as here one
gets incorrect information by just looking at the titlebar (if I got
garbage in the titlebar, this would be less confusing).

2009-03-16 Thread Vincent Lefevre 
retitle 339586 fvwm displays the title provided by WM_NAME instead of 
_NET_WM_NAME
thanks

This should be more clear (but I don't know whether the bug also
occurs under UTF-8 locales). For instance, on the page

  https://bugzilla.mozilla.org/show_bug.cgi?id=315947

xprop -id 0x1c000b8 | grep NET_WM_NAME | perl -ne 'while (/(0x[0-9a-f]{2})/g) { 
printf %c, hex $1 }'

(with the id of the corresponding window) gives:

  Bug 315947 – Window title not updated when a character of the title is 
outside the WM charset - Iceweasel

but FVMW shows the title from WM_NAME instead, which is completely
different.

Bug#488224: Bug#339586: closed by Manoj Srivastava sriva...@acm.org (Re: Bug#339586: fvwm should support the _NET_WM* properties)

And I think that #488224 is not a FVWM bug, knowing the fact that
FVWM uses WM_NAME. According to

  http://tronche.com/gui/x/icccm/sec-4.html#WM_NAME

  4.1.2.1. WM_NAME Property

  The WM_NAME property is an uninterpreted string that the client
  wants the window manager to display in association with the window
  (for example, in a window headline bar).

  The encoding used for this string (and all other uninterpreted
  string properties) is implied by the type of the property. The type
  atoms to be used for this purpose are described in section 2.7.1.

xprop says that the type STRING is used for WM_NAME, and

  http://tronche.com/gui/x/icccm/sec-2.html#s-2.7.1

says:

  STRING as a type or a target specifies the ISO Latin-1 character set
  plus the control characters TAB (octal 11) and NEWLINE (octal 12).

The testcase provided in bug #488224 is based on wish, and according
to xprop, wish does not follow this specification: under UTF-8
locales it uses the UTF-8 encoding instead of ISO latin 1.
