Since chars in kotlin string are code units in UTF-16 encoding, there are some unicode characters that require two consecutive koltin.Char to be stored. These two chars are called a surrogate pair.

ok, how would i handle such

such that it is safe to print a single character of input text of X length without accidentally printing half a Unicode (possibly resulting in a corrupted character)

if that unicode character happens to be directly at the end of X length

such that if it where to be correctly printed a buffer overflow would need to have occured to read 1 character past the allowed X length
