anchor.diff:  The default way of encoding URIs in `UriComponents` works as follows:
   
   . URI variables are expanded.
  -. URI components are encoded individually.
  +. Each URI component (path, query, etc) is encoded individually.
   
  -For each URI component, percent encoding is applied to all illegal characters, which
  -includes non-US-ASCII characters, and other characters that are illegal within a given
  -URI component type, as defined in RFC 3986.
  +The rules for encoding are as follows: within a URI component, apply percent encoding to
  +all illegal characters, including non-US-ASCII characters, and all other characters that
  +are illegal within the URI component, as defined in RFC 3986.

  The above encoding strategy applies `UriUtils.encode(String, Charset)` to each URI
  variable value prior to expanding it. Effectively it encodes all characters with reserved
  meaning, therefore ensuring that expanded URI variables do not have any impact on the
  structure or meaning of the URI.

  ====
  
  The above default encoding strategy *does not* encode all characters with reserved
  meaning, but only the ones that are illegal within a given URI component. If this is not
  what you expect, you can use the alternative strategy described next.
  
  When using <<web-uribuilder,DefaultUriBuilderFactory>> -- plugged into the `WebClient`,
  `RestTemplate`, or used directly, you can switch to an alternative encoding strategy as
  shown below:
