Hello, I was looking up possible solutions to your issues that didn't require that much coding, since I'm still learning, and I noticed the rawurlencode function could do what you need, since rfc 3986 just updates 1738, right ?

Reading through the comments of rawurlencode it seems like it has is not an exact match to rfc 1738. I haven't bothered to finish vetting it yet though as the Twitter docs say the values do not currently contain values that would get encoded.
