Re: Unicode character entry

I am a linguist and I need to type characters from several Unicode

I need an esh I type Ctrl-Shift-u + 283. Keyboard layouts are great
if you need to switch from one language to another, but I cannot use a
keyboard layout because there are too many characters - roughly 140,
plus about 20 optional combining diacritics.

If I upgrade my Fedora 11 to Fedora 13, will I still be able to use
Ctrl-Shift-u + Unicode value? If so, do I have to change the default
settings somehow?

All I can tell you is, after I installed F13, out of the box, the old standby, ISO-standard (as Simos points out), Ctrl-Shift-U + Unicode digits, did nothing in any apps for me.

I'm still trying to find out whether that is by intention or by accident.

I did find a discussion of this (for F12) here:
which mentioned enabling an input method.

I tried their suggestion: System > Preferences > Input Method, which recommended ibus, then I poked around in the preferences there until I found "rawcode" which seemed likely. I also configured Ctrl+Shift+U as the "Enable or Disable" sequence.

After getting that set up, I can enter characters by a /similar/ process as before, but ibus likes to pop-up menus with character choices, and it seems to use the same sequence to enable and disable the input method, so you have to type Ctrl+Shift+U again to disable ibus or it will start up again any time you type a hex digit.

So you can still enter characters by their code point, but it's not entirely clear how to configure it, nor is it so simple to use it for a character here and there.

You might prefer ibus/rawcode, since you need access to more characters and the pop-up prompts it gives might be easier than remembering them all. For me, it's a machine gun for a mosquito.

I also tried the environment variable setting mentioned in the forum thread:

That gives the behavior I'm used to when I set it for individual applications, but I can't figure out where to put it to apply it for everything in my session. So far, I've tried both ~/.pam_environment and /etc/environment to no effect.
