Having issues w/ foreign characters in file/directory names (e.g., ü, ö, حلو) in directory preview pane

[ajponce]

Foreign characters show up as a escaped numbers (e.g., \201) in Dirvish's preview pane when they are found in file or directory names. I didn't expect this, because when using dired, they show up fine. I have been using emacs for years and have tinkered around (i.e., spent a lot of time) adjusting code my init file, but I'm no lisp expert.

These foreign characters also show up fine in the mode-line and header-line buffers when you select the directory in dirvish (the buffers to the left). My guess is that it has to do with the dirvish-define-preview dired function, but I'm not sure where it is going wrong.

I'm attaching a couple of screenshots to show what I'm talking about.
