The first of these characters or "characters", the replacement character, is forbidden because the MediaWiki software uses the replacement character to represent invalid UTF-8 sequences, and cannot differentiate this use as a placeholder from an actual instance of the replacement character.
The characters allowed in a URI are either reserved or unreserved (or a percent character as part of a percent-encoding). Reserved characters are those characters that sometimes have special meaning. For example, forward slash characters are used to separate different parts of a URL (or, more generally, a URI). Unreserved characters have no ...
Even though PHP's urlencode() automatically percent-encodes them, these characters do not get URL-encoded by wfUrlencode(). The ":" symbol is a partial exception – it is not encoded anywhere except for IIS 7.0.
Do not use a semicolon (;) simply to bold a line without defining a value using a colon (:). This usage renders invalid HTML5 and creates issues with screen readers. Also, use of a colon to indent (other than for talk page responses) may also render invalid HTML5 and cause accessibility issues per MOS:INDENTGAP.
ASCII code points that are invalid URI characters may be encoded the same way, depending on implementation. [6] This conversion is easily reversible; by definition, converting an IRI to an URI and back again will yield an IRI that is semantically equivalent to the original IRI, even though it may differ in exact representation.

URL is a useful but informal concept: a URL is a type of URI that identifies a resource via a representation of its primary access mechanism (e.g., its network "location"), rather than by some other attributes it may have.
