1079269 - [Flame] Fira is missing the ℃ and ℉ symbols

Status: RESOLVED INVALID

(Firefox OS Graveyard :: Gaia, defect)

While investigating bug 1073399 I've deleted all Android-specific fonts from my device and this caused the ℃ and ℉ symbols to disappear from the keyboard. After some checking it appears that we're currently picking those fonts from DroidSansFallback as restoring the DroidSansFallback.ttf file fixed the issue for me.

Those characters are present in DroidSansFallback because are used in CJK languages, but aren't really common. The preferred Unicode encoding is °C and °F, that is, ° (U+00B0) plus the normal Latin letters C and F. (See also http://en.wikipedia.org/wiki/Degree_symbol#Encoding).

That leads me to the question: why are ℃ and ℉ in the keyboard? I think the use of those uncommon characters may significantly increase SMS costs, if they're sent correctly at all - for example.

DroidSansFallback is part of the set of fonts we expect to be shipped. It shouldn't be removed. There are a few fonts that we don't actually want to ship, but that's a much smaller set than the one you suggest in https://bugzilla.mozilla.org/show_bug.cgi?id=1073399#c9 .

Closing as per comment 4 as this isn't a bug. We might still want to investigate why we display those symbols in the default keyboard as per comment 3.
