External module "string/utf16-to-utf8-array/docs/types/index.d"

Export assignment utf16ToUTF8Array

• utf16ToUTF8Array(str: string): Array<number>

• Converts a UTF-16 encoded string to an array of integers using UTF-8 encoding.

  Notes

  • The following byte sequences are used to represent a character. The sequence depends on the code point:

    0x00000000 - 0x0000007F:

     0xxxxxxx

    0x00000080 - 0x000007FF:

     110xxxxx 10xxxxxx

    0x00000800 - 0x0000FFFF:

     1110xxxx 10xxxxxx 10xxxxxx

    0x00010000 - 0x001FFFFF:

     11110xxx 10xxxxxx 10xxxxxx 10xxxxxx

  • The x bit positions correspond to code point bits.

  • Only the shortest possible multi-byte sequence which can represent a code point is used.
