Hi, folks. Let me suggest two tips: I've found two pages of Void Linux's users in Japan with instructions about how to configure it to Japanese locale! I suppose you're able to read in Japanese, so there would be no much trouble to understand the instructions there! The first one: 日本語環境 - Void Linuxのメモ:
And the next one, specifically about uim Input Method framework :uim - Void Linuxのメモ:
I couldn't yet read those sites and figure out how to do it (and I'm still a newbie in Linux...!)
To download and install ibus packages and/or other input Methods is easy... The tricky part (at least, for me..) is to configure locales files (which one?, where?, how?...)
If you guys get any success with this issue, please let me know! That is exactly the thing I miss with Void: a easy way to write in 'multi-language' configured within installing process, or through a 'configuration central', as in my current distro (Mageia 5, with KDE... but, with systemd... oh, boy!)
BTW, in Ubuntu 14.04 with Unity, multi-language input is quite easy to set-up, and its GUI works like in Windows! You can get at the same tool the option to change keyboard layout (for non-Latin languages like Russian and Greek, and/or even CTL languages, like Arabic, Hebraic...) and to call an IME (needed to write in Japanese, Chinese, Korean and some others). However, within Mageia /KDE , ibus isn't so 'integrated' ... If I want to write in Arabic (with phonetic layout, 'Buckwalter'!), there's no such option, and I have to call the other app, xkb, to change the keyboard layout properly... Not elegant!
Well, I hope to hear that you found how to set-up language input the way 'We' want!
