thanks for reporting. I merged the fix in this PR #42 feel free to add more properties to "font" and star the project if you like it.

Thanks for the PR.

In the meantime, I wrote a script by myself, nearly from scratch to do the conversion.

Here are the issues I had.

• An input could contain a tag within a tag
• Those tags need to be managed with styles : ['c', 'i', 'b', 'u']
• Some characters are escaped in vtt and not in srt
  • see https://developer.mozilla.org/en-US/docs/Web/API/WebVTT_API#cue_payload

for example:
<c.magenta.bg_black><i.blue>Some italic</i> and normal coloured text. By the way, 2 &lt; 3 !</c>

is well rendered with this output
<font color="#ff00ff"><i><font color="#0000ff">Some italic</font></i> and normal coloured text. By the way, 2 < 3 ! </font>

Here is the script if you want to check the code
