In the omp branch, the server crashes when the player spawn

[dockfries]

Command failed with exit code 3221225477.
Related to the allowMultibyteNicknames function, after using it the player can enter any multibyte language, but the server will crash when the player spawn.

Currently only support the decimal number of bytes from 0 to 232, for 233 to 255 temporarily can not support, because that will cause the server to crash when the player spawn, depending on whether the native function of the omp side can be better supported after.

The latest omp server version no longer has this problem, if it still exists, please check if the callback about the player has a return value, i.e. true/false
