[e-lang] Source code character sets and Unicode

[Ka-Ping Yee]

Hi, all.

I've been thinking and arguing a lot about Unicode issues lately
because of a recently accepted proposal to allow non-ASCII
identifiers in the next version of Python (see references below).

So I thought I'd ask: what are E's policies concerning

  - the character encoding of E source files
  - non-ASCII in comments
  - non-ASCII in string or string-like literals
  - non-ASCII in identifiers

and how, if at all, are these policies likely to change?
