That is not true.  See RFC 2396 section 3.3.  The ":" just like the "+" 
character in the above example is allowed within the path component of 
a URL.  The problem here is that KURL escape encodes/decodes URLs as a
whole instead of on a component by component basis, i.e. path, query, 
fragment etc. RFC 2396 clearly states that characters allowed in one 
component are not necessarily allowed in another and there are characters
that are deemed completely unsafe in all components unless they are escape 
encoded, for example spaces.
