I want to use the Junicode font in articles only for text that is transcribed from old manuscripts. Nothing else on the page will need to use this font. The Junicode font is included in the UniversalLanguageSelector library.
If I load this extension, it does appear that I can choose the font using a CSS class with 'font-family: Junicode;', but not all of the characters display.
I would like to use the ss02 character set, which includes the insular characters. In the documentation it says "ss02 on, language set to Irish". So I tried to use the 'lang="Irish"' setting.
For instance:
<span class="junicode" lang="Irish"></span>
It doesn't seem to do anything.
I can't figure out how to access specific characters, such as the insular t with dot above. On the MUFI website, it says that it is "00F094 LATIN SMALL LETTER INSULAR T WITH DOT ABOVE". If I use  in the text, it renders as the replacement question mark. I can see this character in the Irish_text.pdf included with the Junicode documentation with the Junicode font installed in Windows, but I can't figure out how to get Mediawiki to display it.
Is this possible in Mediawiki? Even if I look at Medieval Unicode Font Initiative on Wikipedia, none of the characters display if I don't have the Junicode font installed on my local system. And when I do have the font installed, this insular t with the dot above does not display.
Thanks.
