#43170 new defect (bug)

Replace all usages of basename() with wp_basename() in order to support multibyte filenames

We still use basename() in a lot of places even though it isn't multibyte compatible out of the box. See http://php.net/basename and https://bugs.php.net/bug.php?id=62119.

Example filename where it can fail: 麻美.jpg

We should replace all uses of basename() with our own wp_basename(). This will probably need a lot of testing, so probably best to avoid one big patch and instead change calls in small chunks.

The above attached patch is just one example where we need to swap it out. I discovered this when writing a unit test for one of my plugins:


I ended up having to clone self::factory()->attachment->create_upload_object() so that I didn't end up with unnamed-file.jpg.
