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.

Fixes ticket #6968

Set relevant filter parameters such that the result can easily be
checked with a waveform editor.
In particular, it makes it clear the silence_start is not accurate in
the current code.

0 is a valid value for silence_start

In mono mode, silence is detected in any single channel instead of all
of them simultaneously
