Add Unicode test to bob

[turnkey-commerce]

It would be instructive to add a case test to bob that includes Unicode characters. The proper handling of Unicode is important with international use of software applications and it would be beneficial for students to know that it exists and how to handle it. Anyone that has had to clean up an issue with Unicode in a code base can relate to this.

The best test case would probably be for the "Shouting" test where it must detect an upper-case Unicode character being present and classify it as shouting, for example: "¡FELIZ AÑO NUEVO!" ("HAPPY NEW YEAR!" in Spanish).

All exercises should be 7 bit ASCII. This is on purpose because many languages have basically no unicode support.

Each track is free to reinterpreted the canonical data and add unicode as they like
