           Summary: Source file without BOM starting with non-ASCII compiles
                    and runs
           Product: D
           Version: 0.174
          Platform: PC
               URL: http://www.digitalmars.com/d/lex.html
        OS/Version: Windows
            Status: NEW
          Keywords: spec
          Severity: normal
          Priority: P4
         Component: DMD

             nThis:


Ä ä;

class Ä {
}

void main() {
}

The above, encoded as UTF-8 without a BOM, compiles and runs just fine even
though the spec claims that "[i]f the source file does not start with a BOM,
then the first character must be less than or equal to U0000007F" which the
"Ä" character is not.

I'm not sure this is a useful limitation, and since it's not taken into account
by DMD it might as well be removed, in my opinion.
