I have written one of these solutions, and it uses an ORC tool specialized
for subtitles, where glyphs are pixel-exact. It can be tricky to use,
especially when it comes to colon and semicolon and to correct a mistake,
but under good circumstances it can achieve a perfect extraction of the text
in a short time. It works well with non-ASCII languages, and has another
rare feature: it can recognize and keep italics.

You may want to give it a try. The source code is there:
