IgnoreDiacritics
is an option for string, grammar, and related functions that specifies whether diacritics should be ignored in strings.
Details
- In grammar functions, IgnoreDiacritics->True specifies that simple transformations such as adding or removing diacritics should automatically be made in attempting to apply grammar rules.
- In string functions such as AlphabeticSort , IgnoreDiacritics->True ignores diacritics only on characters that do not appear in the base alphabet of the language used.
