I agree, but couldn't think of any other way. There are 3 other
unicode options:

	1. A box with an X  (☒ U+2612 BALLOT BOX WITH X)
	2. A bare (unboxed) X (✗ U+2717 BALLOT X)
	3 A bare checkmark (✓ U+2713 CHECK MARK)

I  also found this character:

   U+237B ⍻ not check mark

If you think one of those would work we could use it instead.

I will implement the replacement of the ascii characters with the
unicode and the look at the html checkbox options.

FWIW, there are other issues w/ the active version besides the changes
not being saved -- If you are using hierarchical list or rollups
indicators ([x/y], [x%]), they will not be updated w/o some
javascript.
