Hi again,
I have rethought this matter and I have to revise the statements I've
made earlier. There are two different issues:
1) The implementation of the key-modifiers in load_keycodes() and
send_string() (which I have introduced originally...) is wrong.
Characters which require the use of the group modifier (AltGr) don't
work in the current version of xte. This is probably the problem the bug
reporter is experiencing.
2) Characters which can only be typed using the compose (Multi_key) are
currently not supported. Implementing this feature is not trivial. It
would require to look up the key combination somewhere (e.g. in
/usr/share/X11/locale/en_US.UTF-8/Compose). As mentioned earlier, using
the Multi_key explicitly is a workaround which should work in most
cases. In any case, there should be printed a proper warning/error when
such characters are encountered.
The attached patch addresses these issues and replaces the patch I have
submitted two days ago. I suggest to apply the patch to the upstream
version, as it is not Debian specific. The patch contains the following
changes:
1) All characters that can be typed using a group modifier (Mode_switch
or ISO_Level3_Shift [AltGr]) and/or the Shift key are supported now.
E.g. AltGr+2 = @ or AltGr+Shift+1 = ¡ with a Swiss German keyboard.
2) The following warning is displayed, when an unsupported character is
encountered (this prevents the reported 'BadValue' Xlib error):
Character '%ls' is currently not supported. Using key 'Multi_key'
could be a workaround.
3) The limitation regarding composed characters is now mentioned in the
manpage of xte and an example of a workaround is given:
BUGS
Special characters, which can only be typed using the compose key
(Multi_key), are currently not supported and can't be used in the
argument of the str command. A workaround is to split the string
in two parts and insert 'key Multi_key' in between. For example,
the command sequence
str na
key Multi_key
str "ive
will print 'naïve'.
Cheers,
Marco
