I thought I saw something about utf-8 being able to handle a 31 bit
value..  is that also obsolete/wrong?

how about this for the current encoding scheme:
http://www.unicode.org/versions/Unicode11.0.0/ch03.pdf

Table 3-6.  UTF-8 Bit Distribution
Bits    Scalar Value               First Byte  Second Byte  Third Byte
 Fourth Byte
  7   00000000 0xxxxxxx            0xxxxxxx
 11   00000yyy yyxxxxxx            110yyyyy    10xxxxxx
 16   zzzzyyyy yyxxxxxx            1110zzzz    10yyyyyy     10xxxxxx
 21   000uuuuu zzzzyyyy yyxxxxxx   11110uuu    10uuzzzz     10yyyyyy    10xxxxxx
