functions.php. Wrong ascii characters!!!!!!!!!!!

The code: https://pastebin.com/MWL99YFM

Try getting rid of all of the styled quotes in your code.

Sorry, which are the styled quotes? Yes, I am a noob at website developing.

Every single and double-quote is a styled – rather than a plain – quote. Stick to using a text editor when writing/amending code.

Ahhh ok thankyou, I’ll give it a go.

I’m afraid it didn’t work. Any other ideas?

Can we see the amended code in the pastebin?

This is the amended code: https://pastebin.com/SkEPitz6

When I change all single and double quotes to non-styled quotes, I get this error message:

Parse error: syntax error, unexpected $end in /home/jmadz/public_html/wp-content/themes/coffeebreak-10/functions.php on line 27

Line 27 is the end php bit “?>”.
I’ve check and there is no white space around it.

Ignore lines 1,2,3 and 4 on the amended pastebin. Those are my sidebars.

Ok here’s some more information. When I upload this code:
https://pastebin.com/mvaanLCG

WordPress then changes my functions.php file so it has this code instead:
https://pastebin.com/kgbeFcHX

Maybe that has something to do with it. So then I have to paste in the original uploaded code, into my functions.php file which is already uploaded in wordpress. And when I do that I get those wrong ascii symbols I was firt talking about.
If I leave the code as it is, I get lots of question mark ascii symbols instead. Either way, it’s wrong.

I’m not quite sure that this function is supposed to do but try https://pastebin.com/NAQzHBDt

Thanks for your help esmi. I eventually found a code that worked properly. You were a lot of help though. This question is now SOLVED.
