 - **blacklist(input, chars)** - remove characters that appear in the blacklist. The characters are used in a RegExp and so you will need to escape some chars, e.g. `blacklist(input, '\\[\\]')`.
 - **escape(input)** - replace `<`, `>`, `&`, `'`, `"` and `/` with HTML entities.
 - **ltrim(input [, chars])** - trim characters from the left-side of the input.
-- **normalizeEmail(email [, options])** - canonicalize an email address. `options` is an object which defaults to `{ lowercase: true, remove_dots: true, remove_extension: true }`. With `lowercase` set to `true`, the local part of the email address is lowercased for all domains; the hostname is always lowercased and the local part of the email address is always lowercased for hosts that are known to be case-insensitive (currently only GMail). Normalization follows special rules for known providers: currently, GMail addresses have dots removed in the local part and are stripped of tags (e.g. `some.one+tag@gmail.com` becomes `[email protected]`) and all `@googlemail.com` addresses are normalized to `@gmail.com`.

 - **rtrim(input [, chars])** - trim characters from the right-side of the input.
 - **stripLow(input [, keep_new_lines])** - remove characters with a numerical value < 32 and 127, mostly control characters. If `keep_new_lines` is `true`, newline characters are preserved (`\n` and `\r`, hex `0xA` and `0xD`). Unicode-safe in JavaScript.
 - **toBoolean(input [, strict])** - convert the input to a boolean. Everything except for `'0'`, `'false'` and `''` returns `true`. In strict mode only `'1'` and `'true'` return `true`.
