Unicode Code Point Converter: UTF-8/16 Byte Audit

Inspect code points alongside UTF-8 bytes, UTF-16 code units and JavaScript escape sequences with round-trip evidence.

Quick-win evidence

Scalar values, storage and bytes side by side

Each row distinguishes Unicode scalar value, code-point index, UTF-16 offset/units and UTF-8 byte offset/bytes. Supplementary characters are not mislabeled as two Unicode characters.

Unicode precision boundary

WebToolArc keeps grapheme clusters, Unicode code points, UTF-16 code units and UTF-8 bytes as separate measurements. Normalization follows the browser Unicode implementation; grapheme segmentation uses Intl.Segmenter when available. Property names shown by this tool are limited to the explicit local tables and JavaScript Unicode property escapes used by the page rather than claiming a complete Unicode Character Database name lookup.
