Am I > correct? Right, you're basically describing a ligature. Fonts will support the pre-composed versions using the codepoints you mention and some but maybe not all via ligatures with the underlying character sequences. Note that the explicitly designed version of these glyphs will always be better, because they will be designed to work in an em-box the size of the surrounding text. An algorithmically generated version will be half the size and will thus appear lighter. John Daggett
