How does MathWorld handle character entities, accents, and international characters?
MathWorld uses characters that are defined in the Latin-1 character set DTD (i.e., DTD/xhtml-lat1.ent) together with a select set of Latin Extended A and part of B set (Unicode range 01; see the Unicode PDF chart Latin Extended-A Range: 0100-017F) including for example, the Hungarian lower case o with double acute (ő = ő). Whereever possible, character entities are specified using symbolic entity names (e.g., é = é) instead of numeric ones (e.g., é = é). In cases where character entities are not used, either the closest equivalent Latin character (stripped of accents) or a GIF image is used. Suggestions for additional characters to display as entities are welcome.
