Old Hungaran letters and false chars on wictionary

When I type Old Hungarian text, appear unknown characters. (there are Old Hungarian layout in the xkeyboard-config project in the extras section.)
In the wictionary is shown these symbols.
Roga font installed, but not chooseable globally.

I don't think, if somebody does not follow the international Unicode standard, the priority of bug must be determined as p5 level is good choice.

Hi Gordon, I'm not sure whether it is correct to assign it to you, please feel free to reassign whenever necessary, thanks.

Please be careful! Do not implement the Old Hungarian part of the font with small and capital letters aligned by center horizontal line. It is important that upper and lower case letters are aligned to the bottom line! Unfortunately, the type designers at Apple and Noto have fallen into this mistake!

If you include the ligatures in the font, the ligature k+v is reserved for the "letter" q, the ligature x is the ligature k+s (in Hungarian:k+sz), the ligature j+i (or i+j?) is the "letter" y, and the ligature w is the ligature v+v. In other words: these cannot be discrete ligatures, ZWJ is absolutely necessary. If we look at usability, only consonant + vowel ligatures can be discrete ligatures only ( without ZWJ). If this is not met, the text will be unreadable.
The Old Hungarian ligatures can be found in a side submission.

Some perverted user has requested the ligatures x, y, w, q. I am against its use, the Old Hungarian script is not Latin.

Old Hungarian numbers should be drawn in capital letters.
