I have the following lines in ~/.XCompose:
<Multi_key> <n> <a> <b> <l> <a> : "∇"
<Multi_key> <i> <n> <t> <e> <g> <r> : "∫"
The first line has 5 keys after <Multi_key>, hence it works in firefox, emacs, and konsole. The second line has 6 keys after <Multi_key>, and it seems that's one too long. In emacs it works, in firefox it doesn't work at all, in konsole I get ∫ symbol after the fifth key <g> and I don't need to type <r>.
Of course I actually have more lines in ~/.XCompose, but they are all similar to these two. And it seems that 5 keys is some kind of limit. How do I make it so that all these lines work in all programs?
I am using Debian 10 (Buster), KDE, firefox 68.2.0esr. If I run im-config, it prints the following:
Current configuration for the input method:
* Active configuration: missing (normally missing)
* Normal automatic choice: none (normally ibus or fcitx or uim)
* Override rule: zh_CN,fcitx:zh_TW,fcitx:zh_HK,fcitx:zh_SG,fcitx
* Current override choice: (en_US)
* Current automatic choice: none
* Number of valid choices: 1 (normally 1)
The override rule is defined in /etc/default/im-config.
The configuration set by im-config is activated by re-starting X.
Explicit selection is not required to enable the automatic configuration if the active one is default/auto/cjkv/missing.
