Allow character '#' to be part of a tag
I want to have musical keys as tags and would need # in the tag for the sharp symbol.
For example, tag F#
for a split second, writing #F# shows up correctly as a tag, but is then converted back to text.
Would this work with escape characters?
So, to create a F# tag, I could write
#F\# or #F\\# (I even had to use a \ at the beginning of this line so it doesn't make this line into a large heading
