What about these cases for at-rules and selectors?
// at-rule
@charset "\u00A0";
// selectos
a[id="\u00A0"] {}
Co-authored-by: Masafumi Koba <473530+ybiquitous@users.noreply.github.com>
These are completely relevant test cases, thank you. I have come up with approximately this solution: ...
validate(atRule, cleanQuotedWhitespace(getAtRuleParams(atRule)), atRuleParamIndex);
validate(ruleNode, cleanQuotedWhitespace(getRuleSelector(ruleNode)), zeroIndex);
validate(decl, cleanQuotedWhitespace(getDeclarationValue(decl)), declarationValueIndex);
...
function cleanQuotedWhitespace(value) {
const parsed = valueParser(value);
parsed.walk((node) => {
if (node.type === 'string') {
node.value = node.value.replace(IRREGULAR_WHITESPACES_PATTERN, ' ');
}
});
return parsed.toString();
} All tests pass except for this one. Is my understanding correct that it should no longer be rejected? If so, I should move them to the accept section. |

Can you add more tests?
e.g.
- double quotes
- comments
- properties that accept strings and identifiers (for example
animation-name: "foo", bar;
) - at-rule preludes (for example
@font-feature-values "foo bar" {}
) - etc.

Thank you for the examples!
Some of them are already included, like the comments, and I have added some of yours.

Thanks for adding sufficient test cases. I've left a more suggestion, so can you please take a look?
I have a question. Should we accept or reject this kind of code? a {
grid-template:
"a a\u00A0a" 40px
"b c c" 40px
"b c c" 40px / 1fr 1fr 1fr;
} Syntactically, it's valid CSS, but it produces two cells: 'a' and 'a a'. |

Closes #8558
I have a question.
In the thread, @jeddy3 suggested that ignoring strings might be needed for AtRule, Rule, and Declaration. I’m not sure what cases are possible with AtRule and Rule that could cause this error and that haven’t been covered by tests yet.
In general, I would appreciate it if you could point out such cases.
