These are the normal letters.

These were added because of compatibility issues with East-Asian

These were added because of compatibility issues with East-Asian

character sets.

These are to be used in mathematics, where bold & non-bold characters

If your software supports mark-up, yes. If you want to encode

mathematics in plain text, you'll have to use the mathematical bold,

italic etc. characters. Most mathematical formulæ will require mark-up

for different reasons, though.
