Description

CODE_POINTS_TO_STRING: Takes an array of Unicode code points as ARRAY<INT64> and returns a STRING.

TO_CODE_POINTS: Takes a STRING or BYTES value and returns an array of INT64 values that represent code points or extended ASCII character values.

If value is a STRING, each element in the returned array represents a code point. Each code point falls within the range of [0, 0xD7FF] and [0xE000, 0x10FFFF].
If value is BYTES, each element in the array is an extended ASCII character value in the range of [0, 255].
