Subject Re: guththila_next_char clarification needed
Date Fri, 30 Jan 2009 05:32:28 GMT
Guthtila is written assuming ASCHII characters. So it is not possible to get
negative characters. If Guththila gets negative charactes, it means the XML
stream has ended or contains invalid characters.

Anyway what do you mean by non-ASCII characters? Do you mean binary?
