true if it is ASCII
false otherwise

**Parameters:**
- `string $str The string to be normalized.
` - `bool $keepNonBreakingSpace [optional]Set to true, to keep non-breaking-spaces.
` - `bool $keepBidiUnicodeControls [optional]Set to true, to keep non-printable (for the web) bidirectional text chars.
` - `bool $replaceSeparatorsWithNewline [optional]Set to true, to convert LINE and PARAGRAPH SEPARATOR with "\n".
` **Return:** - `stringA string with normalized whitespace.
` -------- #### remove_invisible_characters(string $str, bool $url_encoded, string $replacement, bool $keep_control_characters): string ↑ Remove invisible characters from a string. e.g.: This prevents sandwiching null characters between ascii characters, like Java\0script. copy&past from https://github.com/bcit-ci/CodeIgniter/blob/develop/system/core/Common.php **Parameters:** - `string $str` - `bool $url_encoded` - `string $replacement` - `bool $keep_control_characters` **Return:** - `string` -------- #### to_ascii(string $str, string $language, bool $remove_unsupported_chars, bool $replace_extra_symbols, bool $use_transliterate, bool|null $replace_single_chars_only): string ↑ Returns an ASCII version of the string. A set of non-ASCII characters are replaced with their closest ASCII counterparts, and the rest are removed by default. The language or locale of the source string can be supplied for language-specific transliteration in any of the following formats: en, en_GB, or en-GB. For example, passing "de" results in "äöü" mapping to "aeoeue" rather than "aou" as in other languages. EXAMPLE:
ASCII::to_ascii('�Düsseldorf�', 'en'); // Dusseldorf
**Parameters:**
- `string $str The input string.
` - `string $language [optional]Language of the source string. (default is 'en') | ASCII::*_LANGUAGE_CODE

` - `bool $use_transliterate [optional]Use ASCII::to_transliterate() for unknown chars.
` - `bool|null $replace_single_chars_only [optional]Single char replacement is better for the performance, but some languages need to replace more then one char at the same time. | NULL === auto-setting, depended on the language
` **Return:** - `stringA string that contains only ASCII characters.
` -------- #### to_filename(string $str, bool $use_transliterate, string $fallback_char): string ↑ Convert given string to safe filename (and keep string case). EXAMPLE:
ASCII::to_filename('שדגשדג.png', true)); // 'shdgshdg.png'
**Parameters:**
- `string $str`
- `bool $use_transliterate ASCII::to_transliterate() is used by default - unsafe characters are simply replaced with hyphen otherwise.
` - `string $fallback_char` **Return:** - `stringA string that contains only safe characters for a filename.
` -------- #### to_slugify(string $str, string $separator, string $language, string[] $replacements, bool $replace_extra_symbols, bool $use_str_to_lower, bool $use_transliterate): string ↑ Converts the string into an URL slug. This includes replacing non-ASCII characters with their closest ASCII equivalents, removing remaining non-ASCII and non-alphanumeric characters, and replacing whitespace with $separator. The separator defaults to a single dash, and the string is also converted to lowercase. The language of the source string can also be supplied for language-specific transliteration. **Parameters:** - `string $str` - `string $separator [optional]The string used to replace whitespace.
` - `string $language [optional]Language of the source string. (default is 'en') | ASCII::*_LANGUAGE_CODE
` - `arrayA map of replaceable strings.
` - `bool $replace_extra_symbols [optional]Add some more replacements e.g. "£" with " pound ".
` - `bool $use_str_to_lower [optional]Use "string to lower" for the input.
` - `bool $use_transliterate [optional]Use ASCII::to_transliterate() for unknown chars.
` **Return:** - `stringA string that has been converted to an URL slug.
` -------- #### to_transliterate(string $str, string|null $unknown, bool $strict): string ↑ Returns an ASCII version of the string. A set of non-ASCII characters are replaced with their closest ASCII counterparts, and the rest are removed unless instructed otherwise. EXAMPLE:
ASCII::to_transliterate('déjà σσς iıii'); // 'deja sss iiii'
**Parameters:**
- `string $str The input string.
` - `string|null $unknown [optional]Character use if character unknown. (default is '?') But you can also use NULL to keep the unknown chars.
` - `bool $strict [optional]Use "transliterator_transliterate()" from PHP-Intl` **Return:** - `string
A String that contains only ASCII characters.
