This makes the output from PGF.showExpr (and other Haskell code that uses the Prelude.show function to show strings) parsable as GF source code in more cases. This is a workaround for the problem that GHC's implementation of the show function uses numeric escapes for printable non-ASCII characters, e.g. show "dålig" = "d\229lig"...
