To clarify, tables are "source" files and should be human-readable, just
as program source code is human-readable. When you need a non-ascii
character in Java, for example, you use the \uhhhh encoding. libloluis
just uses x instead of u.
I have not seen anyone except Mesar advocating for UTF-8 in the tables.
There is a liblouis table called unicode.cti which can be used to find
the hex values of Unicode characters. It contains comments which explain
verbally what each character is.
