D.1. About Locales
- Collation order. The collation order provides language and cultural-specific information about how the characters of a given language are to be sorted. It identifies things like the sequence of the letters in the alphabet, how to compare letters with accents to letters without accents, and if there are any characters that can be ignored when comparing strings. The collation order also takes into account culture-specific information about a language, such as the direction in which the language is read (left to right, right to left, or up and down).
- Character type. The character type distinguishes alphabetic characters from numeric or other characters. For example, in some languages, the pipe (|) character is considered punctuation while in others it is considered alphabetic. In addition, it defines the mapping of upper-case to lower-case letters.
- Monetary format. The monetary format specifies the monetary symbol used by a specific region, whether the symbol goes before or after its value, and how monetary units are represented.
- Time/date format. The time and date format indicates the customary formatting for times and dates in the region. The time and date format indicates whether dates are customarily represented in the mm/dd/yy (month, day, year) or dd/mm/yy (day, month, year) format and specifies what the days of the week and month are in a given language. For example, the date January 10, 1996, is represented as
10.leden 1996in Czechoslovakian and
10 janvier 1996in French.
