I "break reddit" every time I want to give reddit gold to someone else and provide a gift message that contains a special character. I my case I only wanted to say "Joyeux Noël" but even that wouldn't go through. Example (with my own account): https://ssl.reddit.com/gold?goldtype=gift&months=3&recipient=mathieumg&signed=yes&giftmessage=Joyeux+No%C3%ABl
Consistent and reproducible.
Encode gold gift messages as UTF-8
