Ever since I upgraded from KDE4 to Plasma, the keyboard layouts for indian languages have been missing when I try to add them. I know this was an issue before with KDE4, and I had to update my xkb installation - some versions had these language keyboards removed from xkb. I still have an xkb version installed that includes these languages, but they are missing from Plasma's list of keyboard layouts.
I have no idea what needs to be changed, or added, to restore these layouts. Can anyone give me a suggestion as to how to get them back? Does, for instance, kde have a bundled copy of xkb somewhere that needs updating?
If it helps, my operating system is FreeBSD, and I am using the 'KDE5' ports.
