Special Characters in Tags

jason.lange says:
Does anyone know what special (i.e. non-alphanumeric) characters are allowed within tag names? I've done a little manual testing and figured out that the following:

Are Allowed: periods (.), at-symbols (@), plus-signs (+), etc.
Not Allowed: colons (:), stars (*), percents (%), etc.

However, as best as I can tell there isn't a definitive list anywhere.

My interest in this stems from the fact that I am attempting to convert my RTM for use with GTD. Part of what I would like to do is use a unique leading character on certain tags/locations to specify the context and project that each action is part of. Contexts are covered nicely because "@" is supported, but projects would require a different character.

TIA,
Jason

Jason, aside from letters, numbers, and international characters, the valid characters for tags are:

+ - . @ _

(I think they sort in that order.)

Hope this helps!
