Any idea what "Vietnamese IM" folder is?

I have been browsing through my Mac user Library folder while trying to locate my FCPX assets and stumbled upon this folder (screenshot). It is named Vietnamese IM and the folder content seems like a shortcut to my user. FYI I am not Vietnamese, I do not speak Vietnamese and there's no chance I accidentally set my Mac to display in Vietnamese so this folder seems a little out of place and suspect. Can anyone explain please?
