However, it is valid for url_encode() to be passed a 133 1.2.2.2 tls * string that does begin with a slash. For example, the string might 134 1.2.2.2 tls * represent a password, or a path part of a URL that the user really 135 1.2.2.2 tls * does want to begin with a slash. 136 1.2.2.2 tls * 137 1.2.2.2 tls * len is the length of the destination buffer.

Note that only the first character of the src 157 1.2.2.2 tls * string is affected by this flag, and that leading slashes are never 158 1.2.2.2 tls * deleted, but either retained unchanged or encoded. 159 1.2.2.2 tls * 160 1.2.2.2 tls * Unsafe and reserved characters are defined in RFC 1738 section 2.2. 161 1.2.2.2 tls * The most important parts are: 162 1.2.2.2 tls * 163 1.2.2.2 tls * The characters ";", "/", "?", ":", "@", "=" and "&" are the 164 1.2.2.2 tls * characters which may be reserved for special meaning within a 165 1.2.2.2 tls * scheme.
