Direction of secondary weights, used in French. True, results in secondary weights being considered backwards, while False treats secondary weights in the order in which they appear.

For handling variable elements. NonIgnorable is default.

Control the ordering of upper and lower case letters. Nothing (the default) orders upper and lower case letters in accordance to their tertiary weights.

Controls whether an extra case level (positioned before the third level) is generated or not. When False (default), case level is not generated; when True, the case level is generated. Contents of the case level are affected by the value of the CaseFirst attribute. A simple way to ignore accent differences in a string is to set the strength to Primary and enable case level.

Controls whether the normalization check and necessary normalizations are performed. When False (default) no normalization check is performed. The correctness of the result is guaranteed only if the input data is in so-called FCD form (see users manual for more info). When True, an incremental check is performed to see whether the input data is in FCD form. If the data is not in FCD form, incremental NFD normalization is performed.

When turned on, this attribute positions Hiragana before all non-ignorables on quaternary level. This is a sneaky way to produce JIS sort order.

When enabled, this attribute generates a collation key for the numeric value of substrings of digits. This is a way to get '100' to sort after '2'.

Treat all codepoints with non-ignorable primary weights in the same way.

Cause codepoints with primary weights that are equal to or below the variable top value to be ignored on primary level and moved to the quaternary level.

Force upper case letters to sort before lower case.

Force lower case letters to sort before upper case.
