[webkit-help] Fwd: support for unicode

[WoJ]

Hello,

Following a question I posted on Stack Exchange Super User (
http://superuser.com/questions/1017269/is-it-possible-that-a-specific-browser-does-not-support-some-unicode)
I was suggested to reach out to the epiphany mailing list for specific
information.
​I was subsequently redirected to the webkit one. ​
Below is a copy of my initial question.

I wrote a HTML5/CSS/JS application which displays some text in Droid Sans
<https://fonts.googleapis.com/css?family=Droid%20Sans:400,700> (loaded
directly from Google at page load). When developing under Windows, unicode
characters are displayed correctly in Chrome.

I started the application with epiphany <https://wiki.gnome.org/Apps/Web> in
Linux and some unicode characters are not displayed correctly:

   - \u00b0 is fine
   - \ud83d\udd15 is not displayed at all

What could be the reason for that?

   - It should not be the font as the same one is used in both Windows and
   Linux (the remaining of the page looks good).
   - This brings me to the browser: could it be the culprit? (I
   specifically need to use epiphany as others I tried do not support some
   features correctly, CSS' flexbox among others)

In other words: *is it possible that a browser does not
support some unicode characters, others being displayed correctly (and all
of them being fine in another browser on another platform, with the same
font)?*

Thank you for any help regarding this - this character which does not
display is a crossed bell to indicate that alarm clocks are not set at
home, which, as you can imagine, is a national security level kind of issue.

​PS. I initially sent the email from the wrong (not subscription) address.
I believe that my email was rejected (no feedback though), if this is not
the case my apologies for the double post.​
