Elsevier Science Grid characters

[Crissov]

The Elsevier Science Grid in Unicode document by Simon Pepping (@spepping?) and Rob Schrauwen hasn’t been updated since 2004-12-03. Unicode 4.0.1 (or maybe 4.1.0 beta) was state of the art back then.

Unfortunately, not all Grid symbols have been adopted by Unicode. The MathML and STIX effort has had great success for mathematical symbols, which form the majority of our grid symbols. No such effort has yet been done for chemistry and linguistics, two other scientific areas that contribute symbols to the grid. For these symbols, we must maintain a small version of the grid.

Section 3 of the report maps …

1. the grid position, 2. the Unicode point, 3. the valid entity names for this Unicode point, 4. the description of this symbol.

Missing Unicode characters in 2004

Some entries have already been corrected for subsequent Unicode versions.
