Technical Background
Text wrapping (Word Wrap) is a fundamental text processing operation. RFC 5322 specifies email body lines should not exceed 78 characters (recommended) and 998 characters (hard limit). In terminal environments, standard width is 80 columns. Word break handling involves hyphenation rules: English typically breaks at syllable boundaries with hyphens, while CJK languages can break at any character. This tool supports three break modes for different needs.
