Lingua::UK::Jcuken

Lingua::UK::Jcuken is a useful Perl module designed to facilitate the conversion between two layouts on Ukrainian keyboards. With this module, you can easily switch between the Jcuken and Qwerty layouts.

The SYNOPSIS section of Lingua::UK::Jcuken typically contains code examples to illustrate how the module can be used. In this case, you can use the following code to implement the module:
```

If you have Cyrillic characters in the input string, this encoding is also used.
