Philip Langdale af043b839c movtextenc: fix handling of utf-8 subtitles 
See the earlier fix for movtextdec for details. The equivalent bug is
present on the encoder side as well.

We need to track the text length in 'characters' (which seems to really
mean codepoints) to ensure that styles are applied across the correct
ranges.
