Cloudflare worker Pages - is replacing / stripping CSS code


I’m using Cloudflare Pages and it looks like Cloudflare is removing some code once page is generated.

Here an example in my style CSS tag:

content: "\f111";

will be replaced with:

content: "111"; 

How can I solve this? Thank you


We don’t modify your files, if that’s being changed it’ll be either in the build or the browser parsing it differently. I’d recommend building your site and checking the CSS to begin with

When building it locally and running it locally there is no problem. There is also no problem when hosting it somewhere else.
The issue is coming from Clouflare pages.

To fix this problem I have to put double backlash \ as it seems that Cloudflare is removing one backslash, however it’s a problem for external files that we don’t control…
