@BB Just to explain the limitation:-
I refer to characters like accented vowels in any language, diphthongs, umlauts, circonflexes, cedilles, tildes, foreign currency symbols, etc.
The Irish keyboard for English language (on Microsoft Windows or on various flavours of Linux) posesses a certain number of these like accented vowels (fadas), some foreign currency symbols (£ and $), business symbols like copywright, trademark and so on.
But other ones like umlauts, French and Spanish accent characters require one to switch to the French/German/Spanish/etc keyboard.
Many commonly used software packages allow users to type characters from all language-keyboard options that are installed on their operating system. So I can produce these "foreign" characters on my keyboard when I type onto many other things like
* Google Search bar
* Office software like LibreOffice Writer, MS Word, etc
* Text boxes within photo or graphic editing software like GIMP, Inkscape, etc
* Response boxes on forums like Stack Exchange, Stack Overflow, etc
* YouTube Search bar
* LinkedIn posts
* Facebook posts
But some other software packages do not enable this facility, e.g. if it is not anticipated that users of a forum will contribute in a language other than English then non-standard characters may not be supported. In the latter situation, users entering the correct character may see either a plain alphabetic or punctuation character in place of the expected one. Or they may see some weird Cyrillic character.
It appears that AskAboutMoney's forum software (Xenforo) does not allow "foreign" character entry.
More disappointingly still, AAM on Xenforo doesn't even allow Irish fada characters.
A fada shows as Á
a fada shows as á
E fada shows as É
e fada shows as é
So I can't have RTE on AAM with the E showing a fada. I can type the fada-ed E on Google Search and copy and paste it onto AAM - but all I get is still É.
It looks like the AAM Xenforo character encodings need to be reconfigured. This might be a simple thing like reconfiguring the version of the Linux op system running on the server holding the askaboutmoney.com forum web application. If a good range of languages and keyboards are installed on the server's op system, all software running on the server should then interpret a big range of character encodings correctly.
So please refer this issue to the web engineer for your askaboutmoney.com website.
