I’ve asked this before, but perhaps not here. It’s a stubborn issue that I still can’t solve over the past 2 years.
How can I get spell checking for my preferred language to work in Gedit (or Gnome Text edit)?
Both apps have a menu option that allows you to select a spell checking language, the default is US English & there are no other options. There is no method provided to add another lang/dictionary.
Gnome region/lang is UK English.
I would like to have UK English as my spell-check preference in these apps.
gedit uses gspell and gnome-text-editor uses enchant.
See the optional dependencies for enchant:
Optional Deps : aspell: for aspell based spell checking support
hunspell: for hunspell based spell checking support
libvoikko: for libvoikko based spell checking support
hspell: for hspell based spell checking support
nuspell: for nuspell based spell checking support
aspell and hunspell have multiple language packs available.
