Unicode Code Point Adapter

Build a small module that translates between JavaScript strings and arrays of Unicode code points without losing surrogate pair information.

Capabilities

Convert text to code points

• "Hi \\uD83D\\uDE00" yields [72, 105, 32, 128512] @test
• "\\uD83Dabc" yields [55357, 97, 98, 99] preserving the lone surrogate half instead of dropping or replacing it @test

Convert code points to text

• [0x48, 0x69, 0x20, 0x1F680] renders "Hi \\uD83D\\uDE80" @test
• [0xD834, 0xDF06, 0xD800] renders "\\uD834\\uDF06\\uD800", combining valid pairs while leaving the unmatched half untouched @test

Preserve inputs

• Converting [0xD83D, 0xDE03] returns "\\uD83D\\uDE03" without mutating the provided array after the call @test

Implementation
