--------------------------+-----------------------------
 When creating a new media item through the `media` endpoint, CJK and emoji
 characters in the payload file's name are not correctly set as the title
 of the resulting media file.

 While explicitly supplying the CJK filename as a `title` argument works as
 expected, this is not necessary with non-CJK filenames.

 The GUI uploader (media-new.php) handles CJK filenames correctly.


 == Steps to reproduce:
 1. POST a file with filename `日本語.mp3` to `/wp/v2/media`

 Result: `title: {raw: "", rendered: ""}`

 Expected result:`title: {raw: "日本語", rendered: "日本語"}`
