I'm using an american keyboard with Geany, but have recently been wanting to type in some unicode characters.
I don't have an AltGr key on my keyboard, nor do I have any special keys that I can spare to use as a Compose key (I know, most keyboards have a "Windows" key which folks probably usually use for this purpose, but that key is not easily accessible on my keyboard).
After a bit of searching, I found that the common way to get unicode characters (with Gnome anyway) is to hit Shift-Ctrl-U, release, then type in the hex digits representing the unicode code point, then hit Enter. This works nicely on Gedit, and in Firefox too: for example: è, é, ê.
In Geany, to get that to work, first I have to give up using Shift-Ctrl-U for dealing with case (I don't need this feature often anyway, and besides, there's always the menu item for it). Once Shift-Ctrl-U is unmapped though, it still doesn't work well. Geany wants me to *hold down* Shift-Ctrl-U while I type the hex digits (which requires some finger acrobatics), and then when I'm done, although hitting Enter gives me the character I wanted, it also inserts a newline into my file.
I think it would be great if I could enter unicode characters in Geany the same way as with Firefox, Gedit, the Gimp, the Gnome dictionary applet, Gaim, etc.
Thanks, ---John
