Hex character ranges

Greetings,

According to the documentation, it is possible to specify a hex
character to match using '\x' such in '\x2a'.  I was curious if it was
possible to use hex ranges in such expression, like matching \x20a0 to
\x20cf.  If so, can you use some compound logic to make a defintion,
such as
SYMBOL    \x092f|\x0e3f|[\x20a0-\x20cf]

If this isn't possible, please suggest possible work arounds.

Thanks for taking the time to read this,
Matt
