Using % in Gamepass title causing Error with Prompt Purchase?

[kni0002]

I noticed I was getting errors when I used PromptGamePassPurchase with my gamepass which was named “120% Throttle” which had the character “%” in its title. Which threw a huge and ugly error in the output window, to resolve this I had to remove the “%” from the title of the gamepass in order for it to work again.

Error below

Purchase Prompt broken in some games (% character in title)

Closing the loop: this was introduced during the upgrade of internal string library to track Lua 5.2 changes, which makes % replacements illegal unless followed by a digit or %. Unfortunately our own localization script fell prey to this (and seemingly nothing else did?). We’re going to fix the localization script to fix this problem, for now please don’t use % in the product names (note that % followed by a digit never worked correctly, which we’ll be fixing as well). Sorry about this!
