I asked this question in a few places but nobody replied. I'm not sure if Japanese SE is the right place to ask but I'll give it a try.
In Linux I input Japanese with
mozc-fcitx. However, I don't seem to find any way to configure it. By default, full-width characters are entered, which affect even spaces. Is there a way to configure
mozc-fcitx to input half-width characters by default?
