Hello,
Does konsole have escape sequences to (1) switch/set
current encoding, and to (2) query current encoding ?
Also, does konsole support full 24-bit color like urxvt does ?
Thanks

Hello,

Konsole supports an escape sequence to select either UTF8 or the
appropriate codec for the current system locale. ESC-CS-%G for UTF8
and ESC-CS-%@ for the system locale. There is no escape sequence for
setting specific codecs or querying the current codec however.

Konsole supports 256 colours, but not 24-bit colour values.

What is the use case you had in mind?

Regards,
Robert.

Thanks Robert.
The use case is switching the encodings in vim. Sometimes, I
want utf8 in vim, sometimes latin1. Ideally, I want to
vim and konsole be synchronized automatically. Two cases here:

(1) change of encoding via vim setting (utf8<->latin1) would change
encoding of the konsole tab

(2) change of encoding in konsole (utf8<->latin1) tab would
vim to detect it and to set correct it's vim setting of encoding (via quering).

The escape sequences that you gave me, they allow for case (1)
but not for case (2) (querying is missing).

BTW do I understand it correct that different tabs of konsole can
have different encodings ? If this is correct, I don't follow logic of
'current system locale' that you mention. Different tabs can have
different LANG setting and correspondingly different konsole encodings,
correct ? The 'current system locale' is per-process, no ?

When you mean 'current system locale', do yuo mean $LANG
at the time when konsole process was started ? Can't it's
subshells subsequently change their $LANG ?

Thanks
Yakov

Hello Yakov,

Each session (or tab) in Konsole can have a different encoding - but
the LANG variable isn't affected. The encoding is only used to
convert the incoming character stream from the terminal program into a
Qt string which can be drawn on screen. When I said "current system
locale", I meant the locale that is used by default for all KDE
applications.

As with any Unix application, Konsole can only pass environment
variables to a process when it is created. After that it cannot read
or modify them - although the child process itself can.

The escape sequences that you gave me, they allow for case (1)
but not for case (2) (querying is missing).

Do you know the escape sequence used by other terminals for querying /
setting encoding or better, if there is any official 'standard'
sequence which is supported by at least one other terminal that could
be used for this?

Regards,
Robert.

I'll search for existing practice. I'll let you know results of my search.

Hello Robert,
urxvt has escape sequence to query and change urxvt's locale.
However, it is different because it affects urxvt's locale *and*
encoding of all urxvt tabs [1]. Urxvt's sequence seems to me
urxvt-specific and not coming from any "standard". I did not find
anything else.

Yakov

[1] urxvt reference has [2]:

"ESC ] Ps;Pt ST"
Ps = 701 Change current locale to Pt, or,
if Pt is ?, return the current locale (Compile frills).
# change the locale and tell rxvt-unicode about it
export LC_CTYPE=ja_JP.EUC-JP; printf "\33]701;$LC_CTYPE\007"

[2] 'man 7 urxvt' or

Hello Yakov,

Could you file a wishlist bug report against Konsole ( on bugs.kde.org
) to add this in future with the details of urxvt's extensions.

Regards,
Robert.
