Actually i found alot of tickets with similar symptoms, but did not find any solution or workaround.
Currently i experience a problen using IDE shortcuts with Alt modifier. All of them appeared on xpra side as Alt + Meta + SYM instead of Alt + SYM. And that's cause an issue to use any Alt based shortcuts.
Keyboard is meant to get an overhaul in the next release, hopefully we can address this bug too. Please add more info as per wiki/Keyboard
Not heard back - closing.
alt test with keyboard Test inside xpra session (0.10.4)
alt test with keyboard Test windows local (via xpra 0.11 test tool)
With windows machine alt+(numbers) allows typing of non-English characters, such as alt+(0241) = ñ.
Inside xpra session, the shortcut doesn't work (and I'm not aware of any other tricks to use non-English characters, aside from typing them locally and copy/pasting them into an xpra session).
Haven't tested to see if OSX option+(character) shortcuts work, but I imagine they don't.
Attached screen shots from keyboard Test tool, inside xpra session vs. windows local. Let me know if you need more extensive samples, which I can type or somehow copy as needed.
Re-opening. Thanks for the details. Not sure what the OP's client OS was since he never followed up. Sounds like win32.
See http://en.wikipedia.org/wiki/Unicode_input - this is platform dependent and the default X11 input method does not provide a way of entering unicode via numeric values.
See also: GTK+ is an ISO 14755-conformant system. The beginning sequence is Ctrl+⇧ Shift+U and the ending sequence is ↵ Enter or Space. Programs based on GTK+, such as GNOME applications, support Unicode input. - this is no good for us unless we can change the beginning sequence...
This may well require the development/enhancement of an X11 input method to be able to emulate the client's behaviour on the server. (ie: windows Alt+num)
I am closing this ticket because the OP never followed up.
The windows input method is now in a new ticket: #572
Note: 0.14 includes new features related to keyboard input and layout selection:
input-method
switch

See also: #817, #661, #634, #286.
Maybe this is a duplicate of #1119, which was backported to v0.16.x - without feedback from the OP, we will never know.
