whats the benefit to maintaining non unicode spawn behavior? is it needlessly complex to have a spawnA and spawnU and then the actual spawn function determines the more appropriate function to use based on the string itself?
How would it determine that? I don't know that Data.Char.isLatin1 would suffice.
RFC 3629 [1] states: o UTF-8 strings can be fairly reliably recognized as such by a simple algorithm, i.e., the probability that a string of characters in any other encoding appears as valid UTF-8 is low, diminishing with increasing string length. However, no references to the algorithm itself are given. Google brought me this sample algorithm [2]. Probably it's worth to implement something like that and include into utf8-string if it's not already there. 1. http://www.ietf.org/rfc/rfc3629.txt 2. http://mail.nl.linux.org/linux-utf8/1999-09/msg00110.html -- Roman I.
