Description Erik Damrose

Browsers send keyboard events, which are evaluated by noVNC. Different Browsers send varying keycodes for the same key. This cam be problematic for symbol keys, which are not recognized correctly. Examples are backslash and the pipe symbol, which are entered while pressing 'Alt Gr' on a german keyboard.

The keyboard layout can also have an impact, see Bug 20469.

Key events provides by customer for "\" and "|".

Windows 7 IE9, Firefox send the same events in his environment.
Keyboard layout is "Deutsch".

Consider updating to a newer version of noVNC first: Bug #35428
There have been multiple fix and noVNC now also implements the "QEMU RFB extension", which should be a big improvement.

noVNC-1.0.0 supports QEMU's raw keyboard extension:
<https://github.com/novnc/noVNC/releases/tag/v1.0.0>

We really should switch to Debian upstream package (from Buster): Bug #35428

This issue has been filed against UCS 4.2.

UCS 4.2 is out of maintenance and many UCS components have changed in later releases. Thus, this issue is now being closed.
