Cannot type "ć" on Hungarian layout

Plain text programs

In plain text programs such as Gedit or gnome-terminal, do the following:

Right click your open document or the terminal window >> choose Input Methods from the context menu >> and then choose Simple (instead of the default System (IBus (Intelligent Input Bus))

AltGr + 9 + c will now work as intended.

LibreOffice

In LibreOffice, the AltGr/Compose key sequences work as intended, but you need to add Shift to get to the 3rd level:

AltGr (or Compose) + Shift + 9 + c.

Another alternative for inserting this character is to insert its unicode.

To insert a unicode there are two ways:

1st

• Press Ctrl+Shift+U, an underlined u appears;
• insert the unicode and press space or Enter.

2nd

• Press Ctrl+Shift+U and keep holding Ctrl+Shift, the underlined u appears;
• insert the unicode and release the keys.

Using Character Map you can find the unicode u+107 for the small letter ć, and u+106 for the capital Ć.
