after reinstalling Ubuntu, and compiling emacs 29.2, default hebrew font is different

after reinstalling Ubuntu, and compiling emacs 29.2, default hebrew font is different

[Uwe Brauer via Emacs development discussions.]

Hi

After reinstalling my Ubuntu system (now 24.04) compiling emacs29.2
setting 

(custom-set-faces
 '(default ((t (:inherit nil :stipple nil :background "grey98" :foreground "black" :inverse-video nil :box nil :strike-through nil :overline nil :underline nil :slant normal :weight normal :height 160 :width normal :foundry "PfEd" :family "DejaVu Sans Mono")))))


And typing some Hebrew, 

Then, for example lamed is now displayed by 
Libertine Display O-regular-normal-normal-*-21-*-*-*-*-0-iso10646-1
(#x3E0)



             position: 17070 of 17393 (98%), column: 1
            character: ל‎ (displayed as ל‎) (codepoint 1500, #o2734, #x5dc)
              charset: unicode (Unicode (ISO10646))
code point in charset: 0x05DC
               script: hebrew
               syntax: w 	which means: word
             category: .:Base, R:Strong R2L
             to input: type "C-x 8 RET 5dc" or "C-x 8 RET HEBREW LETTER LAMED"
          buffer code: #xD7 #x9C
            file code: #xD7 #x9C (encoded by coding system utf-8-unix)
              display: by this font (glyph code):
    ftcrhb:-PfEd-Linux Libertine Display O-regular-normal-normal-*-21-*-*-*-*-0-iso10646-1 (#x3E0)

Character code properties: customize what to show
  name: HEBREW LETTER LAMED
  general-category: Lo (Letter, Other)
  decomposition: (1500) ('ל')



I'd prefer some Arial font that supports hebrew, and that I have already
installed in ttf format.

How can I achieve that.

Thanks

Customize your fontset by using set-fontset-font.

P.S. This is a question for help-gnu-emacs, not for this list.

No, you didn't.  The above defines the default face's font, not the
font for Hebrew.  I said to use set-fontset-font for a reason.

Because you didn't want it on the devel list.

Ok, I started now emacs -Q


Then the hebrew font is indeed closer to ariel and therefore ok.

However when I press in the menu:
options-->set-default-font-->more-fonts-->select family


Then not only Emacs freezes but my whole Laptop and I have to reboot.

I am on Ubuntu 24, and I tried out various windows manager, gnome,
trinity (a kde 3 fork) always the same result.

I am not sure who is the culprit.

And how to send a bug report.

Any comments, or advice?

"Freezes" for how long?  AFAIR, what you did scans all the fonts on
the system, so if you have a lot of them installed, it can take a
long time.

In any case, it's a different issue.

I'd first submit a bug report to Ubuntu and see what they say.
