 colloquially also known as "matolaatikko."
 
 ## Known limitations
- o Uses a hardcoded letter sheet. Support for reading the key from a file exists.
- o Uses hardcoded 4th group PIAEL -3+1-3-4-2 scrambling when encrypting.
- o Uses hardcoded 4th group -3+1-3-4-2 when decrypting. The key order is brute-forced.
- o Does not support the "second row". Supported replacements:
-   o Swedish numerals (1->ett, 2->tva, etc.)
-   o Space encoded as X
-   o Period encoded as W
-   o Repeating character encoded as C.
