Not a big issue, but capital letters don't seem to work in the Morse Code Algorithm. I understand that Morse Code does not differentiate between upper and lower case letters, but the algorithm dismisses capital letters as if they did not exist. This makes it difficult to cut&paste text into the box.

Also, another picky issue: instead of a 'period' for the dot could you use the "middle dot"? I am not sure if that will help or hinder the appearance -- but just a suggestion.

Here is a sample: ..- .-. vs. ··- ·-·

The middle dot is coded as "middot" or "#183".

Thanks R2 that's a great catch. I'm still recovering from the on-call time and I should look into this soon.
