Graphemes vs code points
Graphemes represent visible characters. Code-point reversal is lower-level and can separate combining sequences.
Reverse characters, words, sentences, or lines while keeping emoji sequences and combining marks intact.
Reverse visual characters, rearrange whole words or sentences, process each line independently, or flip only the vertical line order. Each mode preserves different structure.
Graphemes represent visible characters. Code-point reversal is lower-level and can separate combining sequences.
Reverse whole word order or reverse characters inside each word while leaving word positions unchanged.
Reverse content within every line or reverse the line sequence without changing their contents.
Mirror preview uses CSS only; upside-down mode substitutes supported Unicode lookalikes and reverses order.
It is useful for technical inspection, but grapheme mode is usually the correct choice for human-visible text.
Most order reversals are self-inverse. Sentence reconstruction and upside-down substitutions may not restore every spacing or unsupported character perfectly.
No. It applies a visual horizontal flip to the preview. The underlying output text remains unchanged.
