#canonical_encode_path(path) ⇒ Object

Expands the path, prepends "\?\" and UTF-16LE encodes it. This function is used by the "File" resources where we need convert relative paths to fully qualified paths.

end

#encode_path(path) ⇒ Object

takes the given path pre-pends "\?\" and UTF-16LE encodes it. Used to prepare paths to be passed to the *W vesion of WinAPI File functions. This function is used by the "Link" resources where we need preserve relative paths because symbolic links can actually point to a relative path (relative to the link itself).
