Description Joshua Bell 2012-03-22 04:20:24 UTC 
Section 6.1 - utf-8 encoding

Step 8.2: Append to bytes 0x80 + the remainder of dividing temp by 64^count (as integers).

I believe this should simply be:

Append to bytes 0x80 + the remainder of dividing temp by 64 (as integers).

8.1 already does the shift: temp = code_point >> ((count - 1) * 6)
8.2 just needs to mask off the bits 0x80 | (temp & 0x3f) a.k.a. 0x80 + (temp % 64)
