None that I know of.

Reference the character by name.  Use the Unicode character name
converted to lowercase, and replace spaces with dashes:

   NO-BREAK SPACE --> #\no-break-space

Jade doesn't handle every character name, but it does map
#\no-break-space (I checked).

You can put this in the internal subset of your DOCTYPE declaration:

<!ENTITY nbsp "#\no-break-space">

Note that if you use this &nbsp; entity inside a string, you'll get an
extra "#", and you'll get errors if the entity is immediately followed
by one or more name characters.  The same character in a string would
be represented as "\no-break-space;" (although the ";" can be omitted
if the character reference is followed by a character that cannot be
used in a name, e.g. by a space).
