Missing definition for some utf16 functions

[DongKat]

Hi,
I'm experimenting with building fsxfsmount on Windows. After generating the visual studio solution, I encounter this compile error:

I find this issue stems from missing defintions for libfsxfs_file_entry_get_utf16_symbolic_link_target_size and libfsxfs_file_entry_get_utf16_symbolic_link_target.

Why do I need definitions for these functions?

• I tried building with the UNICODE flags disabled; however, this consistently results in this error: "Unable to run dokan main: unable to assign drive letter\n"
• After some debugging, I found that the mount point argument is being passed as UTF-8, while the Dokan logic expects UTF-16.

Solution

I tested a similar pattern from the UTF-8 variant—libfsxfs_file_entry_get_utf18_symbolic_link_target_size—and had some success. I can open a PR with the proposed changes later.
Please let me know if there are any specific tests that I can run before submitting the PR.
