Research direction

Start with the WebUtility documentation pages for UrlEncode, UrlEncodeToBytes, UrlDecode, and UrlDecodeToBytes, comparing their current conversion descriptions and examples. Done means documenting space-to-plus and plus-to-space conversions where applicable, and correcting the percent-encoded examples to use uppercase %3C and %3E.

Description

area-System.Runtime doc-enhancement Pri3

The documentation for UrlEncode was updated in #3124 to indicate that ' ' is converted into '+' on encode.

However:

The documentation for UrlEncodeToBytes needs the same update.
The documentation for UrlDecode and UrlDecodeToBytes needs a similar update to indicate that '+' is converted into ' ' on decode.
All of these pages give the example that < and > are encoded as %3c and %3e, but this is incorrect. < and > are encoded as %3C and %3E. RFC 3986 says "For consistency, URI producers and normalizers should use uppercase hexadecimal digits for all percent-encodings," and that's what the implementation does.
