Content encoding issues

If you are noticing any encoding errors with your HTML pages, we recommend verifying that the impacted pages are explicitly setting the correct charset in the Content-Type header from your origin for all text/html pages, for example Content-Type: text/html; charset=utf-8. This is particularly important if you are not using UTF-8 encoding. Alternatively you can set the correct charset within the HTML.

If you believe these settings are correct, please inform us. You can find more information in setting the HTTP charset parameter Open external link and in HTML charset attribute Open external link .

Alternatively, you can use a Configuration Rule to disable features that rewrite HTML. This will send the content as-is to the browser.

You also have the option to turn off these features site-wide within the dashboard:

• Email Obfuscation, located in the Scrape Shield section.
• Server Side Excludes (SSE), located in the Scrape Shield section.
• Rocket Loader, located in Speed > Optimization > Content Optimization section.
• HTML Minification (JavaScript and CSS can be left enabled), located in the Speed > Optimization > Content Optimization section.
• Mirage, located in Speed > Optimization > Image Optimization. section.
• Automatic HTTPS Rewrites, located in the SSL/TLS > Edge Certificates section.

Misconfiguring the Content-Type or charset within HTML, or leaving them unspecified can lead to unintended consequences. This can disrupt the intended content presentation, resulting in disorganized rendering and potentially unclear characters. Properly configuring these elements ensures consistent and accurate interpretation, correct HTML modifications, and accurate rendering for browsers. This creates a seamless user experience and aligns with best practices in web development.
