Reverse Text: A Practical Guide
Use Reverse Text to reverse the sequence of Unicode code points in supplied text. It reverses characters rather than reversing only the word order. The result can be useful for simple experiments, but complex writing systems and emoji may not remain visually intact.
How to Use Reverse Text
- Paste the text.
- Select Process.
- Inspect the reversed output.
- Check combined characters and symbols before reuse.
Code Points and Visible Clusters
The implementation spreads the string into code points and reverses that sequence. This handles some characters better than reversing individual UTF-16 units, but it does not preserve every grapheme cluster.
Combining accents, joined emoji and directional text can display unexpectedly after reversal. Reversing text is not encryption and should not be used to protect confidential information.
Worked Example
The text cat dog becomes god tac, not dog cat. If you only want to reorder lines, use Sort Lines or List Shuffler instead.
A visible emoji made from several joined code points may be separated or rearranged by reversal.
Order line entries: use the Sort Lines.
Randomize a list: use the List Shuffler.
Checks and Common Mistakes
- Do not mistake reversal for secure encoding.
- Check combining accents.
- Do not expect word-order reversal.
- Keep the original for comparison.
Frequently Asked Questions
Does it reverse each word separately?
No. It reverses the whole code-point sequence.
Can it safely reverse all emoji?
Not necessarily. Some visible symbols contain multiple joined code points.
Does reversing twice restore the original?
For the same code-point sequence, reversal twice should restore that sequence, though display behavior can still be complex.
