What information was incorrect, unhelpful, or incomplete?
Note that I'm not really familiar with the article content (hence that is why I was looking at it) but It seems weird to see the following example containing a non-encoded ; character :
data:text/html,<script>alert('hi');</script>
knowing that before in the section it is explained that :
If the data contains [characters defined in RFC 3986 as reserved characters](https://datatracker.ietf.org/doc/html/rfc3986#section-2.2), or contains space characters, newline characters, or other non-printing characters, those characters must be [percent-encoded](https://developer.mozilla.org/en-US/docs/Glossary/percent-encoding) (aka "URL-encoded").
And opening the RFC link shows you that ; is a reserved character.
So I'm wondering whether the example is correct. To me, it looks like it should be rewritten to encode the ; reserved character.
If I misunderstood, sorry for the noise.
What did you expect to see?
A correct (not included non encoded reserved character") example (and consistent with the paragraph explaining the reserved character mentioned above).
Do you have any supporting links, references, or citations?
No response
Do you have anything more you want to share?
