• Uppercase: Recognition of uppercase letters only, including accented ones. e.g. "A" (Capital A).

• Lowercase: Recognition of lowercase letters only including accented ones. e.g. "a" (Lowercase a).

• Alpha: Upper and lowercase letters only. This is a combination of (Uppercase | Lowercase).

• Punctuation: Recognition of punctuation signs only. e.g. "!" (Exclamation Mark).

• Miscellaneous: Recognition of other miscellaneous characters only. e.g. "+" (Plus sign).

• All: All characters. Since all elements are enabled, there is no filtering. This a combination of Digit (| Uppercase | Lowercase | Punctuation | Miscellaneous).
