This feature is supported; see the variable `read-quoted-char-radix'.

I suppose that a patch such as the following could be used to support
at least unicode input in `read-quoted-char' (the function underlying C-q).
(set `read-quoted-char-charset' to `ucs' to input unicode-codes)
Whether this is a serious enough problem to consider adding a patch this
latein the release cycle to consider, I don't know. [I think the
default value of read-quoted-char-charset would probably have to remain
nil though...]
