It would be interesting to see whether you did identify all needed locations for multi byte enhancements. Did you look at the Bourne Shell to see where it implements such multi/wide/multi conversions? BTW: I would be happy to check such an enhanced version and compare the performance with other shells ;-) Jörg -- EMail:[email protected] (home) Jörg Schilling D-13353 Berlin [email protected] (work) Blog: http://schily.blogspot.com/ URL: http://cdrecord.org/private/ http://sf.net/projects/schilytools/files/'
