Human view
What a person naturally reads, sees, or hears.
The rendered string may look ordinary while its code points and bytes contain additional structure. The page preserves the original and labels every unusual character before any transformation.
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.
The rendered string may look ordinary while its code points and bytes contain additional structure. The page preserves the original and labels every unusual character before any transformation.
Machine-decodable is receiver-relative. Record the parser, preprocessing, codebook, tokenizer, key, model, and transformation path before generalizing from one result.
The local name map covers common security-relevant characters rather than every assigned Unicode code point. Normalization views are intentionally diagnostic and never overwrite the original evidence.
