I wish people could stop spreading lies about writing systems; giving 3 false information in a single sentence is quite a feat. Of course cuneiform writing is a set of characters, a lot of which being encoded in Unicode starting at U+12000 codepoint. One character doesn't equate a syllable, some even are unpronunced (determiners), and the phonology of Sumerian make its a poor way for its writing system to transcribe English.
