Answer 2

The problem is much wider - "How to make the whole zoo of user devices start to understand Unicode instead of ASCII". (thanks to Moskus for the link to the standard).
The answer is no.

Answer 3

Probably not, if there is no alternative firmware for it that works in full accordance with the standard.
Armenian Radio is wrong about this. The standard says that the SSID is a sequence of 0 to 32 eight-bit values. That is, technically, these are not even character codes - they are just bytes.
In the standard, there are no restrictions on these values ​​(like that the most significant bit of all eight-bit blocks be zero) does not exist.
However, it is common practice to have restrictions in place to avoid input problems.
In version 802.11 from 2012, the ability to interpret the SSID byte sequence, not as single-byte characters, but as multi-byte characters (UTF-8), is unequivocally fixed. This is discussed in section "8.4.2.2 SSID element". The standard itself can be obtained here .
