From what I understand, Pd uses UTF-8 when decoding or encoding
strings. '194 160' (a.k.a hex C2 A0) is the correct byte sequence for
non breaking space in the UTF-8 format. I'm more surprised to see that
the sequences '99 160 99' and '100 194 100' show a meaningful result
instead of a '�'. 

By the way, ASCII defines only the code points from 0 to 127. dec 160
is defined in ISO-8859-1 / Latin1 as non-breaking space. So, it seems
Pd somehow falls back to Latin1 when the input cannot be UTF-8 decoded.
