[Haskell-cafe] Can we improve Show instance for non-ascii charcters?

[Imants Cekusins]

is the purpose of the show :

a) serialization to string?
or
b) text representation?

if a) then why is unexpected display - a concern?
if b) then why is inconsistency - a concern?

if more than one way to display c is possible, then should we expect
both a) and b) from Show?
