Rasmus It seems you have a keen interest in latex + org-entities.
(This might be familiar to you.) You can do a, C-x b *scarath* C-x C-m C-\ TeX C-h C-\ RET and pull all the entities that you ever want in a single go (rather than including them piecemeal-by-piecemeal.) With some scripting, this pulling can be made less laborious but more complete. This is just a note. Nothing beyond that.
