>From the vorbis comment spec:

<p>Content vector format
---------------------
    * A case-insensitive field name that may consist of ASCII 0x20
      through 0x7D, 0x3D ('=') excluded. ASCII 0x41 through 0x5A
      inclusive (A-Z) is to be considered equivalent to ASCII 0x61
      through 0x7A inclusive (a-z).
    * The field name is immediately followed by ASCII 0x3D ('='); this
      equals sign is used to terminate the field name.
    * 0x3D is followed by 8 bit clean UTF-8 field contents to the end of
      the field.

<p>So, there seems to be absolutely no need to escape
