A pygame function or method which takes a file path argument will accept either a Unicode or a byte (8-bit or ASCII character) string. Unicode strings are translated to Python's default filesystem encoding, as returned by sys.getfilesystemencoding(). A Unicode code point above U+FFFF (\uFFFF) can be coded directly with a 32-bit escape sequences (\Uxxxxxxxx), even for Python interpreters built with an UCS-2 (16-bit character) Unicode type. Byte strings are passed to the operating system unchanged.

Null characters (\x00) are not permitted in the path, raising an exception. An exception is also raised if an Unicode file path cannot be encoded. How UTF-16 surrogate codes are handled is Python-interpreter-dependent. Use UTF-32 code points and 32-bit escape sequences instead. The exception types are function-dependent.
