使い方
- Enter text up to 100,000 characters.
- Choose which side receives the mirror, whether to repeat the joining grapheme, and whether each line is processed separately.
- Create the palindrome, review the exact whitespace and punctuation, then copy it or download a text file.
Mirror on either side
Append mode places a reversed copy after the original; prepend mode places it before the original. Repeating the joining grapheme creates an even-length mirror such as helloolleh. Sharing it once creates an odd-length mirror such as hellolleh or ollehello, depending on the side.
Unicode graphemes stay intact
Reversal uses browser grapheme segmentation, so combining marks, emoji modifiers, flags, and joined emoji sequences stay with the displayed character they belong to. Per-line mode mirrors each LF-separated line independently and preserves the line order. Input is limited to 100,000 characters and output to 500,000 characters.
よくある質問
あわせて知りたいこと
Does this test whether my text is already a palindrome?
No. It always builds a new palindrome by mirroring the supplied text. An existing palindrome will therefore become a larger mirrored result.
What does repeat the joining grapheme do?
When enabled, every grapheme is copied into the mirror. When disabled, the grapheme at the join is shared once so the result has a single center.
How are spaces and punctuation handled?
They are part of the text and are mirrored exactly. In per-line mode, line separators remain between the independently processed lines.
