    These are the normal letters.

    These were added because of compatibility issues with East-Asian
    character sets.

    These were added because of compatibility issues with East-Asian
    character sets.

    These are to be used in mathematics, where bold & non-bold characters
    mean different things.

    See above.

    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 formulŠ will require mark-up
    for different reasons, though.
