No, they are in whatever locale the string is. In particular, the entire
keyboard code is filled to the brim with strings, each with a different
locale. I'm talking about functional code here, not something which is
only inside comments.
Another place where everything is with different locaele are the resources.

No can do ASCII. A hebrew "שלום" will not look good, or at all, for
that matter, in ASCII. UTF-8 may work for resources, if the resource
compiler is adjusted accordingly, but not inside the code, where the
encoding actually matters for the code that parses it.

That sounds better, I think... What does perl do with the sources again?

I offered that some time ago. This can also mean that the strings can be
unicode proper. The general consensus at the time was that this should
not be the case, so that the maintainer of the language can easily check

Plus you have not solved the functional strings problem.
