      Your lack of confidence is justified - this won't work.
 
      Flex has in it a widespread assumption that the input is processed
      one byte at a time.  Fixing this is on the to-do list, but is involved,
      so it won't happen any time soon.  In the interim, the best I can suggest
      (unless you want to try fixing it yourself) is to write your rules in
      terms of pairs of bytes, using definitions in the first section:
 
      	X	\xfe\xc2
      	...
      	%%
      	foo{X}bar	found_foo_fe_c2_bar();
 
      etc.  Definitely a pain - sorry about that.
 
      By the way, the email address you used for me is ancient, indicating you
      have a very old version of flex.  You can get the most recent, 2.5.4, from
      ftp.ee.lbl.gov.
