Allow adding single character blocked terms via the API
Twitch's UI allows you to add terms that have only a single character to them. This is good because it allows us to block some characters that are usually used on ascii copy pastes (like "⣿", for example).
Unfortunately, the API imposes a limit of a minimum of 2 characters per blocked term, as seen on the docs:
"The word or phrase to block from being used in the broadcaster’s chat room. The term must contain a minimum of 2 characters and may contain up to a maximum of 500 characters."
This creates a weird behaviour where users can add some terms via the UI, but not via my app (which uses twitch's API) and in the end, from the user's point of view, it just looks like a bug on my app.
Can we make it so that both the API and UI have the same rules, preferably allowing the API to also add blocked terms with a single character so we don't lose functionality?
