This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org. Please check that
the From: line contains a valid email address. After a delay of up
to one day, you should receive an acknowledgment at that address.
Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.
Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug. If you can, give a recipe
starting from `emacs -Q':
----------------------------------------------------------------------
After starting emacs with -Q:
* I set a custom font as default face (eval-region):
(set-face-attribute 'default nil :family "Motix_Round")
Everything looks as expected.
(The font is available here https://github.com/martinp26/motix )
* I resize the default font via C-x C-+:
No ASCII character is displayed correctly, all are represented by a
small box. Unicode characters (e.g., ö (o umlaut)) display correctly.
* If I invoke describe-char on a character of each class I get this:
----------------------------------------------------------------------
position: 221 of 224 (98%), column: 29
character: ö (displayed as ö) (codepoint 246, #o366, #xf6)
preferred charset: unicode (Unicode (ISO10646))
code point in charset: 0xF6
syntax: w which means: word
category: .:Base, L:Left-to-right (strong), j:Japanese, l:Latin
to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"
buffer code: #xC3 #xB6
file code: #xC3 #xB6 (encoded by coding system utf-8-unix)
display: by this font (glyph code)
xft:-unknown-Motix_Round-normal-normal-normal-*-31-*-*-*-m-0-iso10646-1
(#xB8)
Character code properties: customize what to show
name: LATIN SMALL LETTER O WITH DIAERESIS
old-name: LATIN SMALL LETTER O DIAERESIS
general-category: Ll (Letter, Lowercase)
decomposition: (111 776) ('o' ' ')
There are text properties here:
fontified t
----------------------------------------------------------------------
----------------------------------------------------------------------
position: 220 of 224 (98%), column: 28
character: e (displayed as e) (codepoint 101, #o145, #x65)
preferred charset: ascii (ASCII (ISO646 IRV))
code point in charset: 0x65
syntax: w which means: word
category: .:Base, L:Left-to-right (strong), a:ASCII, l:Latin,
r:Roman
to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"
buffer code: #x65
file code: #x65 (encoded by coding system utf-8-unix)
display: no font available
Character code properties: customize what to show
name: LATIN SMALL LETTER E
general-category: Ll (Letter, Lowercase)
decomposition: (101) ('e')
There are text properties here:
fontified t
----------------------------------------------------------------------
* When I reset the size via C-x C-- or C-x C-0 back to normal:
Everything is find again, all characters display correctly.
Workaround:
* If I re-evaluate the face definition after switching to a different
font size:
(set-face-attribute 'default nil :family "Motix_Round")
everything is fine afterwards. The font is used for all sizes from
that point on and displays fine. I assume there is some assumption
about fonts built into emacs that is not fullfilled here but the
font itself seems ultimately fine.
