I doubt that this could have ever worked. The ".." has always been
defined to work for string scalars only over the "ASCIIbetic" ranges
"a".."z" and "A".."Z". Making that work for Unicode scalars would
require extra code of which I see no trace. Not to mention that the
logical semantics for this would be rather ... odd. What should
"a"..chr(0x100) generate, for example?

Hmmm, that *should* work under 'use utf8'.
