+ *
+ * The spec is quite vague in this area, but what is meant is perhaps that it
+ * refers to the character index in the codepage belonging to the language
+ * specified in the subtitle descriptor. Potentially it's designed for widechar
+ * (but not for UTF-*) codepages.

+ * Notes on DDS (Display Definition Segment)
+ * -----------------------------------------
+ * DDS (Display Definition Segment) tells the decoder how the subtitle image
+ * relates to the video image.
+ * For SD, the subtitle image is always considered to be for display at
+ * 720x576 (although it's assumed that for NTSC, this is 720x480, this
+ * is not documented well) Also, for SD, the subtitle image is drawn 'on
+ * the glass' (i.e. after video scaling, letterbox, etc.)
+ * For 'HD' (subs marked type 0x14/0x24 in PSI), a DDS must be present,
+ * and the subs area is drawn onto the video area (scales if necessary).
+ * The DDS tells the decoder what resolution the subtitle images were
+ * intended for, and hence how to scale the subtitle images for a
+ * particular video size
+ * i.e. if HD video is presented as letterbox, the subs will be in the
+ * same place on the video as if the video was presented on an HD set
+ * indeed, if the HD video was pillarboxed by the decoder, the subs may
+ * be cut off as well as the video. The intent here is that the subs can
+ * be placed accurately on the video - something which was missed in the
+ * original spec.
+ *
+ * A DDS may also specify a window - this is where the subs images are moved so that the (0,0)
+ * origin of decode is offset.
