INVALID
(obsolete) A single RUNE follows and is used as the invalid rune for this locale.
The following keywords may appear multiple times and have the following format for data:
<RUNE1 RUNE2>
RUNE1 is mapped to RUNE2.
<RUNE1 THRU RUNEn: RUNE2>
Runes RUNE1 through RUNEn are mapped to RUNE2 through RUNE2 + n-1.
MAPLOWER
Defines the tolower mappings. RUNE2 is the lower case representation of RUNE1.
MAPUPPER
Defines the toupper mappings. RUNE2 is the upper case representation of RUNE1.
TODIGIT
Defines a map from runes to their digit value. RUNE2 is the integer value represented by RUNE1. For example, the ASCII character 0 would map to the decimal value 0. Only values up to 255 are allowed.
The following keywords may appear multiple times and have the following format for data:
