Multiply is at D7 and Divide is at F7; in 5th edition I see: NameStartChar ::= ":" | [A-Z] | "_" | [a-z] | [#xC0-#xD6] | [#xD8-#xF6] | [#xF8-#x2FF] | [#x370-#x37D] | [#x37F-#x1FFF] | [#x200C-#x200D] | [#x2070-#x218F] | [#x2C00-#x2FEF] | [#x3001-#xD7FF] | [#xF900-#xFDCF] | [#xFDF0-#xFFFD] | [#x10000-#xEFFFF] so divide and multiply are not included. The goal is to allow name characters in names, regardess of whether they are in the 7-bit US ASCII set of "letter" or the wider set that people actually use.
