gneto's Issues

URL escaping

Thanks for this very useful software - I use it to read Gemini capsules on a Kindle (by adding a custom CSS). There appears to be an issue with proxying links with escaped URL parameters, e.g. click on any topic here via gneto:

gemini://tobykurien.com/cgi-bin/mailing_list.py

The topic doesn't display as the parameters aren't passed correctly (perhaps something to do with the escaped ?). I noticed a similar issue with Vulpes proxy, although Mozz.us proxy works.

Escape/encode and Unescape/decode queries properly

Gemini does queries slightly differently than Go's stdlib can provide. Use these funcs instead, which are included in go-gemini and the other go-gemini.

// QueryEscape provides URL query escaping in a way that follows the Gemini spec.
// It is the same as url.PathEscape, but it also replaces the +, because Gemini
// requires percent-escaping for queries.
func QueryEscape(query string) string {
    return strings.ReplaceAll(url.PathEscape(query), "+", "%2B")
}

// QueryUnescape is the same as url.PathUnescape
func QueryUnescape(query string) (string, error) {
    return url.PathUnescape(query)
}

The reason this is required is because Gemini does not allow pluses to be used for spaces in queries. They always represent a literal plus sign.
