Human view
What a person naturally reads, sees, or hears.
Many whitespace code points render as blank space while remaining categorically distinct. The laboratory replaces them with labelled boxes and compares conservative and aggressive normalization.
Research boundary: this page uses bounded, inert data and fixed safe examples. It never executes decoded content, requests secrets, calls third-party services, or performs actions against external systems.
Inputs remain on this host. Text operations are size-limited; uploaded files are processed from PHP’s temporary upload and are not retained by the application.
The response will separate summary metrics, representation views, findings, tables, and any generated safe fixture.
What a person naturally reads, sees, or hears.
What a parser, DOM, container reader, or metadata extractor exposes.
What becomes meaningful only with a rule, key, tokenizer, model, or tool.
What normalization, rendering, OCR, canonicalization, or policy changes.
Many whitespace code points render as blank space while remaining categorically distinct. The laboratory replaces them with labelled boxes and compares conservative and aggressive normalization.
Machine-decodable is receiver-relative. Record the parser, preprocessing, codebook, tokenizer, key, model, and transformation path before generalizing from one result.
Collapsing whitespace can destroy legitimate formatting, programming-language indentation, and typographic distinctions. The original is always retained in the result.
