single quote in drawtext

[stavn1]

How do you write a single quote with drawText and videoFilter?

command.videoFilters({
                filter: 'drawtext',
                options: {
                text: 'I\'m here'

            });

but the single quote is omitted, the written text became "Im here".

For anyone else looking for the solution - you have to escape the string a couple times - this worked for me

text.replace("'", "\\\\\\'");

If anyone can't manage to make this work, try this string.replace(/'/g, "\u2019"); from https://stackoverflow.com/a/26963014/6605412

That doesn't work at all, unless you are using double quotes in your syntax. My syntax doesn't accept double quotes. So it's really dumb, how this lousy program has no way to get around that. Really frustrated since this crap accepts escaping the single quote with two single quotes, but it doesn't work.

Based on @David-Development's answer and the linked stackoverflow post, here's my function to escape all the potentially bad characters in the drawtext filter:

function escape(text) {
  return text
    .replaceAll("\\", "\\\\\\\\\\\\\\\\")
    .replaceAll("'", "\\\\\\'")
    .replaceAll("%", "\\\\\\\\\\%")
    .replaceAll(":", "\\\\\\\\\\\\:");
}

I don't see a strong reason why options.text for filter: drawtext shouldn't be automatically escaped. Should this be a pull request?

For

text = "sample-text%'"

this works

text = text.split("%").join("\\\\%") 

but this doesn't work

text = text.split("'").join("\\\\\\'")

So I am using

text = text.replace(/[\\\%\'\:]+/g, " ")
