Certain Xcompose sequences do not work in GTK applications (but work fine in other applications)
I recently started using XCompose to finally be able to enter these unicode symbols that I need fairly regularly. Unfortunately, some of the XCompose codes I set up only work in KDE applications, they do not work in GTK applications:
# Works fine everywhere
<Multi_key> <bar> <minus> : "⊢"
<Multi_key> <minus> <bar> : "⊣"
<Multi_key> <s> <e> <p> : "∗"
<Multi_key> <asterisk> <asterisk> : "∗"
<Multi_key> <p> <t> <s> <t> <o> : "↦"
<Multi_key> <l> <a> <t> <e> <r> : "▷"
# Does not work in GTK
<Multi_key> <m> <a> <p> <s> <t> <o> : "↦"
<Multi_key> <a> <l> <w> <a> <y> <s>: "□"
Is it possible that GTK has some kind of length limit or so for these shortucts? It would be great if that limit could be increased so that GTK is compatible with other X11 applications.
