  *     example of how a variant character works, take LATIN SMALL LETTER Y
  *     WITH DIAERESIS, which is typicially 0xDF in EBCDIC.  Step 1 converts it
  *     to the Unicode value, 0xFF.  Step 2 converts that to two bytes =
- *     11000111 10111111 = C7 BF, and Step 3 converts those to 0x47 0xE7
+ *     11000111 10111111 = C7 BF, and Step 3 converts those to 0x8B 0x73.  The
+ *     table is constructed so that the first bytes of a variant will always
+ *     have its upper bit set (at least in the encodings that Perl recognizes,
+ *     and probably all).
  * 
  * If you're starting from Unicode, skip step 1.  For UTF-EBCDIC to straight
  * EBCDIC, reverse the steps.
