\0 as-is. Characters outside this range (Unicode ordinals 1-256)

are treated as errors. This includes embedded NULL bytes.

Error handling is defined by the errors argument:

NULL or "strict": raise a ValueError

"ignore": ignore the wrong characters (these are not copied to the

output buffer)
|
|
"replace": replaces illegal characters with '?'
|
|
|
|
Returns 0 on success, -1 on failure.
