I would think other symbols should be avoided like commas, single/double quotes, and apostrophe come to mind; plus non-viewable characters like tabs & device codes. Then there is the question of unicode characters, which ones in, which ones out. Ligatures could be messy Filesystems, domain servers and HDF have similar restrictions & condundrums. In terms of a generic sw development project, probably best to have an api that tests or corrects for acceptable text strings within the program.

Although the position will be created, the reset command will not properly access the position key. What are the allowable characters?
