How it works

Decode complete UTF-16LE units for strings and retain termination/trailing-data diagnostics. Read integer bytes in the selected order using exact unsigned arithmetic.

The example bytes encode A, a NUL, B, and two NUL code units, producing the two strings A and B.

Limits

Value bytes only, not a whole .reg file or registry editor. Unicode string mode is explicit; ANSI variants are excluded. Environment references stay literal. No setting, registry key or file is changed.
