Hi,
I think I've worked out what's happening with the rendering of the
website on Clive's laptop. Perhaps it will help someone spot why.
The large buttons have text appearing over the top of them. What should
be a button with
Change
Password
in it has ‘key_circle’ overlaid. This is intended to be a single
character in a ‘symbol’ font chosen by the website.
It becomes a single character through a bodge exploiting ligatures
within fonts. Intended to render words like ‘piffle’ as ‘piffle’, the
feature is abused by defining a ligature for the run of characters
‘key_circle’. This causes the browser to search for ‘key_circle’
through all the text using the font and replace it with the ligature.
In this case, it will be a single character that will presumably look
like a key in a circle. This being a suitable icon for the ‘Change
Password’ button.
The font isn't being used. This is the underlying problem.
‘key_circle’ isn't found in the ligature table of the fallback font and
so remains as ten characters.
Why isn't the font loading on Clive's laptop giving he has disabled all
add ons? Ideas please.
Clive, in Firefox's settings, can you check General → Fonts →
Advanced... → ‘Allow pages to choose their own fonts, instead of your
selections above’ is ticked.
