Alphabet Structure - MetaTrader 5 Library | MT5 EA Download - MetaTrader 5 Resources

This structure provides quick access to lowercase and uppercase Latin and Russian characters, numbers, punctuation, brackets, spaces, and special sets of symbols where spaces should be removed before and after.

I find this useful in applications where text data needs to be manipulated.

The alphabet also contains methods for classifying characters/text.
