I am talking specifically about the issue of Ada folding rules with
Latin-1 and ten years experience with them. You seem to be talking
about different issues entirely. Note that I talked about the folding
rules above. I think you did not read carefully, and thought I said
that people were happy to write in Latin-1. That of course is false.
That is why GNAT has always provided -gnatiw to allow full 16-bit
characters in identifiers, and it is why the new standard has
mandated this, and extended it to all planes of 10646.
