DynDll does not work with non-ASCII characters in path

[NotNite]

See: https://github.com/SlopCrew/SlopCrew/issues/134

My mod Slop Crew uses DynDll to load GameNetworkingSockets inside of Unity. When the path to the library contains non-ASCII characters, a cryptic error is thrown:

[Error  : Unity Log] EntryPointNotFoundException: No matching entry point found for GameNetworkingSockets_Init in SlopCrew.Common.Native

(For the sake of testing, I renamed Bomb Rush Cyberfunk to Bómb Rush Cyberfunk.)

This is a problem because r2modman installs profiles into AppData by default, so users with non-ASCII characters in their Windows username will not be able to use my mod.
