This is an updated/modernized version of a small hack I previously posted here:
https://www.mobileread.com/forums/sho...80#post3004080
It moves the hyphenation dictionaries from the system partition to the user partition in
.addons/hyphendicts/ so you can edit them easily, and even add new ones for other languages [whether Kobo will actually use them is another matter], or disable hyphenation altogether by removing/renaming the dictionary files.
Filenames for hyphenation dictionaries must be like
hyph_xx_YY.dic, all other files will be ignored.
To uninstall, create .addons/hyphendicts/uninstall
Note that uninstalling will not restore the original hyphenation dictionaries... you get those with every firmware update, or just keep a backup of the original files and put them in .addons/hyphendicts/ before uninstalling.
Update: Didn't work for GloHD/KA1
