### Transliteration Example (Portable ASCII vs. Stringy)

Source: https://github.com/voku/portable-ascii/blob/master/README.md

Demonstrates the transliteration functionality of Portable ASCII compared to the Stringy library. Both achieve the same result of converting accented and non-ASCII characters to their closest ASCII equivalents.

```php
<?php
// Portable ASCII
use voku\helper\ASCII;
ASCII::to_transliterate('déjà σσς iıii'); // 'deja sss iiii'

// voku/Stringy
use Stringy\Stringy as S;
$stringy = S::create('déjà σσς iıii');
$stringy->toTransliterate();              // 'deja sss iiii'
```

--------------------------------

### ASCII Conversion Example: to_ascii()

Source: https://github.com/voku/portable-ascii/blob/master/build/docs/base.md

Illustrates the use of the `ASCII::to_ascii()` static method for converting strings containing special characters to their ASCII representations, with language-specific transliteration rules.

```php
echo ASCII::to_ascii('Düsseldorf', 'de');

// will output
// Duesseldorf

  echo ASCII::to_ascii('Düsseldorf', 'en');
  
// will output
// Dusseldorf
```

```php
charsArray(bool $replace_extra_symbols): array
// Returns an replacement array for ASCII methods.
// EXAMPLE: 
// $array = ASCII::charsArray();
// var_dump($array['ru']['б']); // 'b'
// Parameters:
// - bool $replace_extra_symbols [optional] Add some more replacements e.g. "£" with " pound ".
```

```php
charsArrayWithMultiLanguageValues(bool $replace_extra_symbols): array
// Returns an replacement array for ASCII methods with a mix of multiple languages.
// EXAMPLE: 
// $array = ASCII::charsArrayWithMultiLanguageValues();
// var_dump($array['b']); // ['β', 'б', 'ဗ', 'ბ', 'ب']
// Parameters:
// - bool $replace_extra_symbols [optional] Add some more replacements e.g. "£" with " pound ".
```

```php
charsArrayWithOneLanguage(string $language, bool $replace_extra_symbols, bool $asOrigReplaceArray): array
// Returns an replacement array for ASCII methods with one language.
// For example, German will map 'ä' to 'ae', while other languages will simply return e.g. 'a'.
// EXAMPLE: 
// $array = ASCII::charsArrayWithOneLanguage('ru');
// $tmpKey = \array_search('yo', $array['replace']);
// echo $array['orig'][$tmpKey]; // 'ё'
// Parameters:
// - ASCII::* $language [optional] Language of the source string e.g.: en, de_at, or de-ch. (default is 'en') | ASCII::*_LANGUAGE_CODE
// - bool $replace_extra_symbols [optional] Add some more replacements e.g. "£" with " pound ".
// - bool $asOrigReplaceArray [optional] TRUE === return {orig: string[], replace: string[]} array
```

```php
charsArrayWithSingleLanguageValues(bool $replace_extra_symbols, bool $asOrigReplaceArray): array
// Returns an replacement array for ASCII methods with multiple languages.
// EXAMPLE: 
// $array = ASCII::charsArrayWithSingleLanguageValues();
// $tmpKey = \array_search('hnaik', $array['replace']);
// echo $array['orig'][$tmpKey]; // '၌'
// Parameters:
// - bool $replace_extra_symbols [optional] Add some more replacements e.g. "£" with " pound ".
// - bool $asOrigReplaceArray [optional] TRUE === return {orig: string[], replace: string[]} array
```
