The Text Utilities and the International Resources

Many of the Text Utilities routines script-aware, which means that you need to understand script systems and the international resources to use the routines properly. Each script system contains a collection of these resources, which contain data and routines that define how regional differences are handled. In particular, the international resources contain tables that define how different text elements are represented.

The resources used by the Text Utilities are

• the script-sorting ('itlm') resource, which defines the sorting order among scripts
• the numeric-format ('itl0') resource, which describes details of how time,
  numbers, and short dates are presented
• the long-date-format ('itl1') resource, which describes how long dates
  are presented
• the string-manipulation ('itl2') resource, which contains tables that define how strings are sorted and which characters cause breaks between words
• the tokens ('itl4') resource, which contains tables that define which sequences of characters create which tokens

The appendix "International Resources" in this book describes each international resource in detail.
