Fortress (sun's possibly-not-vaporware hpc language) supports arbitrary unicode chars in code, and has an escape syntax for commonly used things. Similarly, proof-general/isabelle supports tex-style escapes for symbols & greek. It seems to me that a pre-processor that turns human-friendly escapes (e.g. \{lambda} rather than some magic number) into unicode and a slightly intelligent IDE (or emacs mode?) would go most of the way to letting us use up-side-down ys and curly as with all the visual beauty and editor niceness that we have now with ascii.

How can I convince ghc version 6.5.20060919 to accept latin1 characters in literals?
I wish to keep source files (containing umlauts in strings) that can be compiled by either ghc-6.4.2 and ghc-6.6.
You can use numeric escapes like "\222".
