Panic in markdown-json-cite with non-ASCII input

[SamWilsn]

The following (also attached) causes a panic:

---
eip: 3
---

Some text somewhere that needs a citation. [^1]

[^1]:
    ```csl-json
    {
      "author": [
        {
          "family": "Mazières"
        }
      ]
    }
    ```

The panic:

$ eipw --config ../config/eipw.toml eip-3074.md
thread 'main' panicked at /home/sam/.cargo/registry/src/index.crates.io-6f17d22bba15001f/annotate-snippets-0.9.2/src/display_list/from_snippet.rs:275:9:

Hey @SamWilsn , would like to work on this task - can you assign me that. Could you clarify the remaining tasks for this issue? Any additional context would be appreciated. Thanks!

This is pretty much it. Take the attached input, and fix the panic. Any fixes would be very appreciated!
