Hi,
und da stößt man dann auf gen-delims und sub-delims. Um das zu verstehen muss man dann wieder suchen und suchen: Für sub-delims habe ich z.B. in dem Dokument zwar gefunden, welche Zeichen diese sind, nicht aber welche Funktion sub-delims haben.
Und um nachfolgendes zu verstehen, muss man schon sehr versiert sein in der Internet-Welt:
The purpose of reserved characters is to provide a set of delimiting
characters that are distinguishable from other data within a URI.
URIs that differ in the replacement of a reserved character with its
corresponding percent-encoded octet are not equivalent. Percent-
encoding a reserved character, or decoding a percent-encoded octet
that corresponds to a reserved character, will change how the URI is
interpreted by most applications. Thus, characters in the reserved
set are protected from normalization and are therefore safe to be
used by scheme-specific and producer-specific algorithms for
delimiting data subcomponents within a URI.
