Then don’t use it and you are not welcome to understanding it isn’t an issue here, but with the programs used to write the original article.
Do a bit or research for smart quotes and straight/dumb quotes and all the stuff one needs to do to use them or not use them.
Oh...and you are not welcome! Sheesh
It shouldn't take a lot of development time to insert some code that goes "Scan each character of the posting. If the character is one of the troublesome characters, replace it with the best corresponding 'dumb' characters".
Really. I'm increasingly convinced that FR is not being actively maintained.
Believe me, as an experienced web developer of many years, it is NOT an issue outside of this site, nor does using 3rd party tool constitute a fix. This is something that the maintainers of FR need to deal with.
I didn’t mean to be harsh with you, but I’ve seen people brow beaten for not using a 3rd party tool to run their article through before posting here, as though that’s some kind of actual fix for this problem.
The only real fix for it, lies with the maintainers of the code for this site and they don’t seem to be doing much to tackle the problem.
