Another – Replace bug html unicode chars
-
Hi Guys
I have found that html characters are getting replaced by unicode values and breaking mt LMS course content. It happens when I replace file that is referenced in my course.
My courses saves the content in a postmeta value field structured in a JSON format. Any Character that is an inverted comma gets converted to u2019. Any double quotes get converted to u201d
This is saved and then my course code cannot parse the JSON data and fails to load.
This does not happen in version 3.4.1 (which I have rolled back to)
I have tried fully removing the plugin and reinstalling it with 3.4.2 but the error keeps happening.
This is a link to a screen capture of a diff I did of small part of the course content before and after replacing file.
Before is on the Left, after on the Right

We are using the CleverCourse LMS system.

They save the course contents into a postmeta field.
This is a sample you could use to test with.
[{"lecture-section":"[{|gq2|lecture-name|gq2|:|gq2|test2|gq2|,|gq2|icon-class|gq2|:|gq2||gq2|,|gq2|pdf-download-link|gq2|:|gq2||gq2|,|gq2|allow-free-preview|gq2|:|gq2|disable|gq2|,|gq2|lecture-content|gq2|:|gq2|<p>|gq6|Nunc rhoncus|gq6| justo id sem tincidunt, eu congue augue venenati's.

Donec aliquam orci eget ante iaculis, in ullamcorper mauris lacinia. Aliquam libero ante, ultricies quis diam nec, dictum laoreet nisl. Integer ac turpis eu sapien cursus tristique.

You’ll probably need to associate that image in the media library with the post you create.
Once you have that content above in your database (not sure how you’ll do it without CleverCourse, perhaps create a post with custom meta field called “gdlr-lms-content-settings” and put it in there.) then go to your media library and do a simple replace of the the image. As that image is associated with a particular post, the meta data get changed and all the ” and ‘ get swapped for unicode.
I hope that helps.
