I would object, as I expect to be able to put values in the range 0 to 
1114111, or at the very least the range of Unicode that people would 
use... 65535 is probably not enough. I'd recommend storing strings as 
either UCS-4 or UTF-8, but in the latter case you have variable number of 
bytes to take care of. Internally, I believe that UCS-4 (32-bit encoding) 
is full good, as Pd's lists of floats are gonna be encoded over 64-bits or 
128-bits anyway (wasting nearly half or 3/4 of the bits depending on 
whether you have a 32-bit or 64-bit OS/mode).

What's important to me is that the Pd user does not struggle with making 
pd interpret UTF-8 variable-length encoding, and instead struggles with 
making pd work with lists of characters, which is already enough work 
anyway. I like that [list length] gives me the number of characters and 
not the number of bytes, because the latter is rarely significant.
