The thing with the Emacs \x escape is that anyone using it for characters
outside of ASCII is asking for pain, and always has been. It has only ever
been clearly defined for that character set; any existing code in the
repository for other characters, for example, _will definitely_ break with
the merging of the Unicode branch.
We are miscommunicating. Whether it is wise to use \x is not the
question. The issue I am talking about is that of _coherence_
(parallelism of syntax) between \x and \u.

The \u syntax (with a fixed number of digits) came into wide use with Java
in 1996. The necessity for the \U extension arose with progress towards
version 3.0 of Unicode and its ~1.1 million available code points. That
version of the standard was released in 1999; the C99 ISO standard for C of
the same year included both \u and \U. Various other C-oriented programming
languages have incorporated the syntax since.
Thank you, but my question here is not about \u. Rather, it is about
whether there are OTHER incompatibilities between Emacs Lisp and C
string syntax.
I want to see that information before deciding what to do here.
