Description Gleb Popov freebsd_committer freebsd_triage 2018-07-25 10:01:39 UTC 
Running

(gdb) set charset UTF-8

returns

Undefined item: "UTF-8".

this makes it impossible to debug some programs with UTF-encoded constants and also breaks KDevelop unittests [1].

Can anything be done with that?

Comment 1 Luca Pizzamiglio freebsd_committer freebsd_triage 2018-07-26 16:05:23 UTC 
Sure.
I'm digging into the issue.
Apparently, the system libc iconv doesn't provide the support that gdb wants.
Switching to the libconv in ports, will extend the support to 200 charset.
I guess, I'll add an option (ON on default) to use extend the charset support.

Nice finding.
