Unicode Utilities

The Unicode Utilities provide a number of different utilities that use and demonstrate features of the Unicode encoding and locale data. These include the following:

  • bidi - Unicode Bidi Algorithm (UBA) Demo
  • bnf-regex - Simplified regex generation
  • breaks - Unicode Segmentation
  • Changes
  • character - Unicode Character Properties
  • confusables - Visually Similar Characters
  • idna - Internationalized Domain Names (IDN)
  • languageid - BCP47 Language Tags
  • list-unicodeset - Manipulate sets of Unicode characters
  • properties - Unicode Properties and Values
  • regex - Generate corrected regex
  • transform - Transform strings using CLDR
  • unicodeset - Compare sets of characters

Common to many of the utilities is the use of UnicodeSet. For more information, see list-unicodeset - Manipulate sets of Unicode characters
