Problem with encoding

Hi there, I have a new computer working under Ubuntu. When using Firefox I often have a problem with the characters which appear when I open webpages or even read pdf documents. This isssue does not seem to happen in a very consistent way (some websites will appear correctly one day and incorrectly another day). I include below a screenshot as example. The problem does not seem to appear with chromium... If you have any idea about how to fix this I would be very grateful Thanks Michael

As a test you can try to disable the Italic style for this element.

You can right-click and select "Inspect Element" to open the builtin Inspector with this element selected.

You can check in the Rules tab in the right panel in the Inspector what font-family is used for selected text. You can check in the Font tab in the right panel in the Inspector what font is actually used because Firefox might be using a different font than specified by the website.

Hi Michael, for the photo caption, when I check the site, it says the photo caption is Arial Bold Italic. Could you compare on yours using the Page Inspector tool:

  • right-click the unicode boxes and choose Inspect Element
  • after Firefox opens the Inspector, on the right side, change from the displayed panel to the Fonts panel (you may need to use a little triangle at the end of the bar that says Rules Layout Computed Changes Fonts Animations)

Here Firefox should show what the page calls for and what Firefox is actually using for that element.

Hi, thanks for your answers. When I disable the italic on the element it appears correctly. How can I globally disable the use of italic with Firefox?

Disabling Italic was merely meant as a test.

We have seen cases where Firefox tries to use the Twemoji font that only includes emojis and not normal ASCII characters for displaying Italic text.

Is this happening in your case as well if you check the font that is used in the Font tab in the Inspector like suggested above ?

yes, this seems to be indeed the problem (Firefox using Twemoji font). From your answers on the other threads, do I interpret correctly that there is no known fix to this issue? thanks again for your help!

You can try to set gfx.e10s.font-list.shared = false on the about:config page.
