Allowing characters to span more than one column wouldn't break the layout rule, as long as the character to column mapping is generally agreed upon across editors and locales. (I think we established that this is not necessarily the always case, although in practice it should be).
I guess we can just refer to the Unicode standard for the mapping?
It's not part of the Unicode standard, but see http://www.unicode.org/unicode/reports/tr11/ Note that there's a special category for "East Asian ambiguous", which could not be sensibly assigned a width. Personally, I'd vote for making it an error to write something like
x = y where y = z z = 5
and add a compatibility mode to compilers. The Haskell standard doesn't have a notion of "warnings", does it? --Dylan
