I know my response was not completely to the question in the original post -
I was branching off a bit to the status of ":". But then, any substabtive
statement about file: URIs tends to get clouded soon after it is uttered.
As to what the rfc says, it also contains this charming bit of language -
" In general, a character is reserved if the semantics of the URI changes if
the character is replaced with its escaped US-ASCII encoding."
But, as the text says elsewhere,
" only the mechanism responsible for generating or interpreting that
component can determine whether or not escaping a character will change its
so this bit does not give much practical guidance with respect to the
notorious file: scheme.
BTW, I could not find where the rfc actually says what you mentioned. What
section is that, John?
