Symbols: ^ and ~ not found in Hama IR320 system

Question

I am trying to setup a Hama IR320 system. However my Wifi (WPA2) password contains ^ and ~ symbols. I cannot find them anywhere in the predefined list of characters:

or

Is there an alternate way to define Wifi password (other than this UI), or am I missing something here ? I can see there is a http server running on this radio.

Turns out the list of characters has three funky entries:

After multiple trial and error attemps, I was able to find the matching symbols:

This one is the ~:

And this one is the ^:

The first one (red circle) is the plain dash symbol -.

For reference, the above was done on the following sofware version (ir-mmi-FS2026-0500-0104_V2.6.20.EX63089-1B11):

Here is a possible confirmation for the above interpretation. One can download the firmware directly from here (follow the download link) using known firmwares:

Which then gives:

We are able to find back the symbols ~ and ^ in the right order and expected location (direct neighboors).

One fun deduction is that the following glyph:

is actually the * character (someone to verify?).

There seems to be something odd about the symbole £, which does not display nicely in the hexdump output, maybe this one is not what it looks like (someone to verify ?).

I did report the issue upstream, and vendor made a fix. I have not checked but this seems to be fixed in 2.6.20.EX63089-1B12.
