Old Hungarian (or Szekler/Székely) writing

 * Cinnamon version: 4.6.6
 * Distribution: Mint 20
 * 64-bit

Issue

1. Please add the script (eg. Latin, Runic, Szekler) to the keyboard selector when there are multiple same language, but with different scripts, keyboard layouts installed.
2. Please add the Old Hungarian (Unicode block) to Linux Mint. a) This would enable the characters to show when selecting Preview in Linux Mint's Keyboard (see image below) b) This would enable the characters to show when visiting https://en.wikipedia.org/wiki/Old_Hungarian_(Unicode_block) c) This would enable LibreOffice 7.0 to work correctly (see image below)

Steps to reproduce

Enabling Old Hungarian keyboard

Linux Mint Menu → Preferences → Keyboard → “Layouts” tab → Enable “Include less-common layouts in the selection list” → Click “+” → Select “Old Hungarian” → Preview

Click “Add” → Close “Keyboard” window

Keyboard Selector in System Tray Instead of having 2 Hungarian keyboard layouts showing, would Linux Mint please show:

• Hungarian (Latin)
• Hungarian (Runes) or Hungarian (Szekler)

Expected behaviour

Show same language keyboards which are based on different scripts with the script. For example, these keyboards would be listed as:

• Hungarian (Latin)
• Hungarian (Runic) or Hungarian (Szekler)

Other information

Can the 2 Hungarian keyboard layouts please be differentiated when they are enabled as they are based on different scripts, i.e. Latin and Runic/Szekler?

A solution could be similar to how Linux Mint differentiates programs when the PPA and Flatpak versions are installed. For example, LibreOffice and LibreOffice (flatpak). They keyboards could be shown as Hungarian (Latin) and Hungarian (Runic)/Hungarian (Szekler). What do you think?

Transliteration to Old Hungarian in LibreOffice 7.0 https://wiki.documentfoundation.org/ReleaseNotes/7.0#Transliteration_to_Old_Hungarian

As an RTL (Right-To-Left) AutoCorrect feature in Hungarian, words, numbers and some kind of punctuation are transliterated to Old Hungarian (or Szekler/Székely) writing, turning on the right to left writing direction using Writer's Complex Text Layout support during typing (László Németh) tdf#133589

Transliteration of “Székely írás 2020-ban” (“Szekler script in 2020”)

Thank you

If the Old Hungarian keyboard is installed, can Linux Mint automatically install the required fonts?

Would the fonts at https://github.com/googlefonts/noto-fonts/blob/master/hinted/NotoSansOldHungarian/NotoSansOldHungarian-Regular.ttf work?

Once the fonts from the link are installed, the keyboard layout is:
