Which working well at multiple sites, but on mine, on multilangual part /en/ I got error reported n Microsoft Edge when you open it localhost:1313/en/index.xml.
This page contains the following errors:
error on line 278 at column 185: PCDATA invalid Char value 31
I investigated that and found that {{ .Summary | html }} containing characters that’s braking XML format.
Cannot use safeHTML in <description> (I am using in <content:encoded>).
Any other way to remove strange characteds from .Summary?
Tried plainify but still no change.
Identified which post summary is breaking that and it’s following:
When I moved to Hugo with my website, I looked to optimise everything and implement new techniques. Once Safari gain native WebP support back in 2020, I implement WebP following PawelGrzybek.com - WebP and AVIF images on a Hugo website. The post introduced not only how to implement WebP (at the time when Hugo <0.83 haven’t support it), but also shown how to go step further by implementing AVIF.
This method require you to have WebP/AVIF files stored along with PNG/JPG and not relay on rendering them when the site is build.
I was interested in implementing this as well, but after some tests in my environment I decided not to, and here I will explain why (and it is not about browser compatibility — Safari incompatibility).
Yes, I struggle to find this in functions but yes, its working.
It replace <p> to that <p> which is desirable in <description>, where the 1st is desirable in <content:encoded> when used (and I used it with safeHTML)
Found the issue.
It’s nothing above and the code is all correct.
I go back to the markdown file in Visual Studio Code (previously used Atom) and found, highlighted in red strange invisible character that was breaking the whole thing. When I removed that all start working.
