Guile's mistake is that it does lots of pointless conversions from utf8 strings
to wide-char arrays, and back, which is a) a cpu suck, and b) a breeding
ground for bugs. The current 2.1 guile, in git as of a few weeks ago, has
multiple utf8 handling bugs.
I believe most or all of these bugs are "internal", fixable without any
changes to the API or user code. Its just that the utf8 unit tests for guile
are weak, and don't test some of the common usages, and thus allow bugs
to breed.

Well, yes, that too.
