How to parse URL strings?

[gogo9th]

Hi,

I Find Katana parser really useful and thanks for developing this tool for us. I just realized the following is not parsable:

@font-face {
font-weight: 700;
src: url(https://fonts.gstatic.com/s/ytsans/v8/46kqlb3ta3zqoJU2dfPhb0xg0mlY.woff2);
}

Is there any way for us to include styles that start with @?

I solved the above issue, but Katana seems to have a bug: it cannot parse the stylesheet below:

My error is:

src/katana.tab.c: 2808
--- number.raw = (KatanaParserString){"to", 4};
+++ number.raw = (KatanaParserString){"to", 2};

But there is still an error for this:

.rp_userbox-container::before {
}

@supports (align: auto) {
}
