Hi, the site uses the font Monotype Corsiva. Firefox didnt display this font, but is using sans-serif. If I try opera or konqueror from kde 4.6, the site is displayed correctly. 
The font is also installed in KDE.

Firefox under Windows is fine. I use Opensuse 11.4 here. The same issue is under Ubuntu (I just checked it in an VM)

Please give me a hint if you need any other information. 


Reproducible: Always

Steps to Reproduce:
1.Open Firefox under linux
2.Open the Website
3.is not displayed correctly
Actual Results:  
MT Corsiva font is not used

Expected Results:  
MT Corsiva font is used.

Please confirm where the font is installed on your system; e.g. run the command

  fc-list -v | grep Corsiva

and paste the resulting output here.

Sorry, I was distracted....

I'm a bit puzzled by this output from "fc-list -v"; I'd expect it to also show the pathname of the font file, e.g. something like  file: "/usr/share/fonts/truetype/......"

Please try

    fc-match -v :family="Monotype Corsiva" 

and report the output of this.

I'm wondering what exactly is meant by this. Note that Firefox is not a KDE application, so if the font is installed in some KDE-specific way, that might explain why FF doesn't find it. Firefox relies on fontconfig to locate fonts on Linux, which is why I'm curious about the result of fc-match; this will tell us what fontconfig finds when it is asked for "Monotype Corsiva".

(I don't have Monotype Corsiva on my Linux system, so can't directly compare my own results. AFAIK, this is not a freely-available font, and does not ship with typical Linux distros, so it cannot be expected to be universally available.)

I know that FF isnt a KDE application. Just mentioned it in case it is important.

You could download the font from the website I mentioned.

Hello, just to remember: the problem is still here. Firefox 11 under opensuse 11.2 x64. Fonts are installed under /usr/local/share/fonts/m/MTCORSVA.ttf and /usr/local/share/fonts/v/vivaldin.ttf

please let me know if you need any other informations

Greetings

Hi,

after two years with no progress: The problem is still alive. I´ve switched my system to Ubuntu 13.10 64bit with the installed firefox and have the same results as ever. Chromium Browser under Ubuntu and Firefox under Windows works fine. It seemed to me, that nobody wants to fix this.

Comment 11

[Jonathan Kew [:jfkthame]]

I looked into this a little. The problem here arises because the Monotype Corsiva font (the only face in its font-family) is marked as being Italic, but the site does not call for font-style:italic in its style information. If it added that property, the expected font would be used.

The font matching code in gfxPangoFonts is failing to fall back to the Italic (and only) face of the Monotype Corsiva family when we request a Regular one.

It looks like gfxPangoFonts[1] aims to implement the font matching algorithm from CSS 2.1[2], which said (roughly speaking) that if no face with matching font-style (regular or italic) was available in the first family, it should fall back to the next. However, the algorithm has been revised for CSS3 Fonts[3], so perhaps the SlantIsAcceptable check should no longer be applied?

Attachment: mismatched font-style should not cause a specified font-family to be skipped altogether

Removing the SlantIsAcceptable check does not break any of our current tests (https://tbpl.mozilla.org/?tree=Try&rev=733c0225410e), and better matches the current CSS Fonts spec, AFAICT.

Thanks for the links.  Using an italic font when an upright style is requested is usually bad, so I don't understand the choice of spec wording, but I assume other platforms already do that, and this patch makes the behavior closer to the CSS3 algorithm.
