Compares two strings in a case insensitive manner.

Case folding is applied to the two string arguments which are then compared with the == operator.

Arguments

• string_a and string_b are two strings to be compared

• type is the case folding type to be applied. The alternatives are :full, :simple and :turkic. The default is :full.

Returns

• true or false

Notes

• This function applies the Unicode Case Folding algorithm

• The algorithm does not apply any treatment to diacritical marks hence "compare strings without accents" is not part of this function.

Examples

iex> Unicode.String.equals_ignoring_case? "ABC", "abc"
true

iex> Unicode.String.equals_ignoring_case? "beißen", "beissen"
true

iex> Unicode.String.equals_ignoring_case? "grüßen", "grussen"
false
