Comment (by jipmoors):

 The problem lies in the implicit character coding assumption.
 The `esc_textarea` assumes the supplied content has been written inside
 the CMS and thus conforms to the charset selected.

 A quick test with a duplicate of the function without the implicit
 encoding shows the file as it is saved on disk.
