the subset of the following productions for which the appropriate
style bit is set are checked in order (using the conventions of
RFC 2234, RFC 2396, and RFC 2732; UCS4 stands for any UCS4
character):

replacing "\" by "/" within <*UCS4>
Production T5 (DOS; FSysStyle::Dos only):
ALPHA ":" ["\" *UCS4]

"file:///" ALPHA ":/" *UCS4
replacing "\" by "/" within <*UCS4>
Production T6 (any):
*UCS4
becomes
"file:///" *UCS4
replacing the delimiter by "/" within <*UCS4>. The delimiter is
that character from the set { "/", "\" } which appears most
often in <*UCS4> (if FSysStyle::Unix is not among the style bits, "/"
is removed from the set; if FSysStyle::Dos is not among the style
bits, "\" is removed from the set). If two or more
characters appear the same number of times, the character
mentioned first in that set is chosen. If the first character
of <*UCS4> is the delimiter, that character is not copied.
