For instance, I want an ampersand in D&D, but it gets filtered out.

You can't. You can spell out "and" instead. Like [ponies-and-unicorns]


Unfortunately, this is not possible.

From the Ask Question page, the only allowed characters for tags are: a-z, 0-9, +, #, -, .

However, I do have a solution:

  • Create the tag using the name spelled out in full, using hyphens to separate the words.
  • Create a tag synonym mapping [dd] to the full name tag.

The latter will ensure that anyone who tried to type 'd&d' in the box will have the proper tag put on the question. This works because the ampersand is silently stripped from the input, resulting in an actual input of [dd]. Hopefully using [dd] for this doesn't collide with another tag you actually need.


How about [dnd] instead?
