What this tool proves

Explicit Unicode interpretation

Code points are integers, not UTF-8 bytes or UTF-16 code units. Supplementary characters therefore produce one value even when JavaScript stores a surrogate pair.

One character view becomes an ordered scalar-value list

Code points are integers, not UTF-8 bytes or UTF-16 code units. Supplementary characters therefore produce one value even when JavaScript stores a surrogate pair.

The output never guesses a numeric base: U+, 0x, and decimal formats are separate, visible choices.

Unicode text stays scalar, private, and bounded

Every operation rejects lone UTF-16 surrogates before processing. Inputs are capped at 256 KiB, report operations at 20,000 code points, and output at 1 MiB.

The work starts only after submission and stays in the current browser tab. Tool Swim does not upload text, call the developer API, retain results, or save presets.
