I've certainly considered type ambiguity, but I don't know how bad it
will be in practice.
My small experiments indicate that things would work well.
As for IsChar, the intention of that class is to have just one
instance. The only reason for introducing it is to keep the instance
declaration of IsString conforming to Haskell-98.

Have you considered possible type ambiguity issues? There may be a
case for generalising "++" to the Monoid class, but that might not
work well with this.

There will never be any implicit conversion. Any overloading you
create will have to decide how to treat the [Char].

I'm suspicious, but as long as a Char is never ever implicitly
coverted to an integer type such as Word8, I suppose it might be OK.
I will rant about this on request.
