Comment (by subrataemfluence):

 @MattyRob,

 I tested by modifying regex pattern in `function wp_ajax_delete_theme()`
 with your suggestion (`[^A-z0-9._\-]/`) but it did not work. The original
 error message ("Deletion failed: The requested theme does not exist")
 disappeared but the following new message is now coming up:

 "'''Deletion failed: Could not fully remove the theme theme.period.'''"
 and as expected the theme was neither removed from admin UI nor physically
 from the disk.

 `$theme_dir` variable however outputs the correct path.
