I guess we should try following the RFC. Thanks.

[go-nuts] html/template: urlEscaper uses small letters to escape, whereas URLQueryEscaper uses capitals
i noticed that html/template escapes a URI using small letters. For
example, the following code outputs "%e5%af%bf%e5%8f%b8", not "
%E5%AF%BF%E5%8F%B8".
t, _ := template.New("foo").Parse(`{{define "T"}}{{end}}`)
t.ExecuteTemplate(os.Stdout, "T", "寿司")
(See https://play.golang.org/p/9caza-3ojur )
This behavior is different from what template.URLQueryEscaper does. Also,
this is invalid with URL Standard (
https://url.spec.whatwg.org/#percent-encoded-bytes ). RFC 3986 Section 2.1
says "For consistency,
URI producers and normalizers should use uppercase hexadecimal digits for
all percent-encodings."
It seems that this line
generates
these small letters. So we can fix this just by changing x to X.
But this behavior has remained for several years. Therefore I want to
confirm that this should be fixed, before filing an issue or sending a pull
req. Am I missing something?
