Hello everyone,

For the following post, I'm getting incorrect facet responses.

Post Url: https://bsky.app/profile/testjjzz.bsky.social/post/3lbwoz6effs2m

Response:

"createdAt": "2024-11-27T13:50:05.980Z",
"langs": [

],
"text": "😀 #abcdef",
"$type": "app.bsky.feed.post",
"facets": [
{
"features": [
{
"tag": "abcdef",
"$type": "app.bsky.richtext.facet#tag"
}
],
"index": {
"byteEnd": 12,
"byteStart": 5
}
}
]
}

Could someone please explain how to properly utilize facet information for this post?

Thank you!

The offsets are correct, note that they're utf8 byte indexes, not codepoint indexes or anything else.
