[BUG] Vapoursynth not recognizing subtitles for harcoding.Neither does Avisynth

[Maria111]

Dear Mr Selur,

First and foremost thank you for that quite versatile video encoding and filtering program.Unfortunately,in this version of your program (August 2020),I have a problem.It does not at all recognize the ass or srt subtitles I am trying to hardcode with it.The Last version that worked properly for me on that matter was a very old one (2019.01.02.1),but it led to crashes with vspipe memory leak all the time.Since I have 16gb of ram and an i72600 cpu,I think that this was not normal behaviour.

The language of the subtitles is Greek and the encoding utf-8. It worked flawlessly in the old version if it managed not to crash before the vspipe leak.When I enable the subtitles, avisynth shows an error and vapoursynth shows a blank preview window.I put a fake subtitle with english characters,still the same.Is there a way to fix this,as I see you have added new filters in this version and I would like to use them?The OS is Windows 7 utimate 64bit,if it matters.I am trying to funsub a really old anime and it helped a lot to clear,deblock and upscale the video and also burn the subtitles in one go to minimize quality loss.It is a pity too,because vapoursynth had really good ass subtitle support.

I apologize for any mistakes as English is not my native language.I hope you are able to fix the problem.Thank you in advance.

Yours sincerely,
Maria111
