All alphabets are scripts, but not all scripts are alphabets:
some are syllabaries or ideograph collections. (Yes, the word
"ideograph" is a misnomer.)

"Character set" is not really a well-defined term. Here are the
usual terms:

        character repertoire: a collection (set) of characters
        coded character set: a mapping between integers and characters
        character encoding standard: a mapping between sequences of
                octets and characters
        charset: a MIME synonym for "character encoding standard"

A font is a mapping from glyph codes (which are often the same as
character codes) to glyphs. A typeface is a collection of related
fonts differing in size, weight, etc. A glyph collection is a
collection of glyphs. :-)
