This one was one of the best I could find: http://barzilai.org/math_sym.htm That's a nice overview, but only a small subset of available unicode characters (see http://www.unicode.org/charts/symbols.html).

Especially when thinking about OAI, I'm really wondering if _any_ standards or agreements apply ? Does anyone know how they do this in big reference repositories ? In our library system there is a coding rule for the handling of sub- and superscripts. Carbon dioxide (HTML COsub2/sub) would be coded CO_2 and the Uranium Isotope 238 (HTML sup238/supsub92/supU) as 238_92_U. This is not useful for reading and understanding (because the coding results are ambiguous). But while coding the metadata this way it is possible to formulate (and transform) queries that can match the metadata. Maybe I was just unlucky after looking for a few references, but it doesn't seem that these submissions in Arxiv include special symbols: http://arxiv.org/abs/0811.1165 http://arxiv.org/abs/0811.0548 They use TeX and hope that anyone can understand it.

Re: [Dspace-tech] How to enrich metadata with special characters?
Unfortunately there were no responds to my question. Whenever You include a markup-language in the field values, You will have problems during searching. When You search for example for carbon dioxide as 'CO2', and You encoded it as 'COsub2/sub', You will never find it! A possible way to solve the problem would be to split metadata values into two fields: one for harvesting / indexing and one for presenting - like dc.title and dc.title.display. Then it would (theoretically) be possible to include something like HTML or TeX in the presentation field and allow DSpace to render it, while doing the search on the normal field. But to do the rendering one must modify the DSpace code... We still have no practical solution for this problem.
