The EnhancedUnicodeMaps setting

Use the setting EnhancedUnicodeMaps in KCM Core Administrator to control how MAP indices are handled. If this setting is enabled, all MAP indices are stored as Unicode and compared using the function compare_characters (see compare_characters). Without this setting the characters used in MAP indices are limited to the character set Latin-1.

You can use the pragma "EnhancedUnicodeMap" to override the setting EnhancedUnicodeMaps in the Master Template.
