hi, when i type in jconsole in the terminal i cannot enter äöü etc. they just do not appear.

i know you cannot use them as identifiers but thats not the issue, i want to be able to use them in strings.

it is possible to do so in jqt and jandroid, so i would consider this a bug.

note too, that it is not a problem with my terminal, as i can type them without any issue as long as i am not in the jconsole repl.

i really need this to work, because i want to write my code in neovim and send it to the repl from there - i cannot send it to jqt.

thanks for the awesone work,

kind regards

You didn't tell which platform and terminal you are using.
I think it depends on platform and terminal.
I have no problem entering accent characters or chinese on macbook jconsole.

jconsole use libedit to implement readline functions. Apparently libedit in Linux doesn't support unicode or it needs special interface to do it.
As a workaround you can disable readline function with the -norl parameter, eg
$ jconsole -norl

very weired as libedit should now support unicode by default. anyhow, the workaround seems to work, thanks!

bilam commented

what is the version of your libedit.so ? Is it 2.x or 3.x ?

herrvonvoid commented

my the version my packagemanager tells me is 20221030_3.1-1, so i guess 3.1

j9.4.2 has a commit
jconsole -noel to disable libedit but not linenoise
which enable linux jconsole to handle unicode and readline functions.
