What is text reversal?

Text reversal means completely reversing the character order of a piece of text. For example, reversing "Hello" becomes "olleH". This tool uses JavaScript's Array.from() method to correctly handle Unicode code points, ensuring that emoji and multi-byte characters (such as Chinese, Japanese) are not corrupted after reversal.

What is the difference between the three reversal modes?

"Reverse entire text" reverses all characters as a whole; "Reverse each line" keeps line order unchanged but reverses characters within each line; "Reverse each word" keeps word order unchanged but reverses characters within each word. For example, input "abc def" with word-by-word mode yields "cba fed".

Why is Unicode support needed?

Ordinary string reversal methods (like split("").reverse().join("")) will break UTF-16 surrogate pairs, causing emoji and other characters to become garbled. This tool uses Array.from() to correctly split by Unicode code points, ensuring all characters (including emoji, CJK characters) display correctly after reversal.

What does "preserve original line breaks" mean?

When "Preserve original line breaks" is checked, even in full reversal mode, lines are reversed individually, keeping the line count and line break positions unchanged. If unchecked, line breaks are also reversed in full mode, which may cause line break positions to change in the output.
