The Text Encoder Decoder scans input in a single pass using Unicode-aware string operations. Grapheme clusters, line breaks, and whitespace rules follow Unicode Standard Annex #29.
Regular expressions and delimiter rules identify tokens, words, sentences, or custom patterns. Case sensitivity and locale options are applied before counting or transforming.
Processed text is emitted with preserved or normalized line endings as selected. Copy-to-clipboard output matches the on-screen result exactly.
