Can Moodle handle diagrams, mathematical symbols and foreign character sets?
Yes. Moodle has the ability to display complex mathematical formulae, diagrams etc. using TeX. This uses the Moodle “filter” feature, so the TeX filter must be enabled for you by your Moodle Administrator. The TeX filter generates graphical representations so no additional software or fonts is required on viewing computers. Moodle is fully Unicode and can handle a huge range of international characters. Note, however, that you still need to ensure that the required fonts are available on the client computers.
