In our library system there is a coding rule for the handling of sub- and superscripts. Carbon dioxide (HTML CO<sub>2</sub>) would be coded CO_2 and the Uranium Isotope 238 (HTML <sup>238</sup><sub>92</sup>U) 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.
