It's what encoding into UTF-16 uses for characters that don't have a Unicode
equivalent, such as raw bytes.
Now:
(encode-coding-string "X\377Y" 'utf-16be)
=> "X Y" (in UTF-16-BE)
With the patch:
(encode-coding-string "X\377Y" 'utf-16be)
=> "X\ufffdY" (in UTF-16-BE)

Do you mean that on balance, all things considered, you prefer space as
replacement character to U+FFFD?
