Well, then there is some bitter irony in this, so it allows pretty
much everything,
but does not allow me to beautify code with hyphens.
I can fully understand the wish to use non-latin scripts in strings or comments.
As for identifiers, IMO, apart from latin letters and underscore, the
first unicode candidate
I would add is U+2010. And probably the LAST one I would add.
