## Description

When you use [Options]-[Permalinks]-[Common Options]-[Date and name based], or %
postname% in custom URL, entry title will be normalized for fitting to URL permitted
letters. If title has non-ASCII letters, those letters cannot be directly put in
URL so they are percent-encoded. This is processed in sanitize_title_with_dashes_original()
and utf8_uri_encode() .

The reason capital letters in percent encoding required is described on RFC3986 
section 2.1,

> The uppercase hexadecimal digits ‘A’ through ‘F’ are equivalent to the lowercase
> digits ‘a’ through ‘f’, respectively. If two URIs differ only in the case of hexadecimal
> digits used in percent-encoded octets, they are equivalent.

For consistency, URI producers and normalizers should use uppercase hexadecimal 
digits for all percent-encodings. As you see RFC2119 section 3, “should” means you
may ignore it with valid reason.

This plugin makes regular URL by which percent encoding was carried out with a capital
letter.
