ISO8859-1 implementation

Table 6 shows the ISO8859-1 (Latin-1 alphabet) locale categories.

Table 6. Default ISO8859-1 locales
__use_iso8859_ctypeSelects the ISO8859-1 (Latin-1) classification of characters. This is essentially 7-bit ASCII, except that the character codes 160-255 represent a selection of useful European punctuation characters, letters, and accented letters.
__use_iso8859_collateSelects the strcoll/strxfrm collation table appropriate to the Latin-1 alphabet. The default C locale does not require a collation table.
__use_iso8859_monetarySelects the Sterling monetary category using Latin-1 coding.
__use_iso8859_numericSelects separation of thousands with commas in the printing of numeric values.
__use_iso8859_localeSelects all the ISO8859-1 selections described in this table.

There is no ISO8859-1 version of the LC_TIME category.
