problem with UTF-32 characters, like: 🍀 or 💕

[fpv999]

those UTF-32 characters ( like U+1F340) are stored in 4-bytes sequences, starting with 0xD8xx ... thus in one moment Unity Text components receives only a first-half of the UTF-32 character, which leads to crash like this:

ArgumentException: invalid utf-16 sequence at -1819518832 (missing surrogate tail) Parameter name: string

Thanks for the issue report! Unfortunately we are just maxed out with how many projects we can support actively. I do hope to get back to TextTyper in the next few months, at which time I'll add more improvements and bugfixes. But right now I'm not gonna be able to look into this.
