Describe the bug / provide steps to reproduce it

Deno's web app framework "Fresh" uses file-based routing, similar to Nextjs. So in order to create a dynamic route, you create a file with square brackets in the name. E.g. blog/[slug].tsx

When using Zed, it seems the language server does not work in any of these files. None of the language-server intelligence features work, and saving a file (with format_on_save) does not format the file, it throws the following error in the status bar:

Formatting failed: failed to format via language server: unexpected character at index 34. Click to see logs.

Logs:

2024-11-22T09:57:38.924075-05:00 [ERROR] failed to format via language server

Caused by:
    unexpected character at index 34
2024-11-22T09:57:39.185874-05:00 [WARN] Generic lsp request to deno failed: unexpected character at index 34
2024-11-22T09:57:39.18688-05:00 [ERROR] unexpected character at index 34

Note: Unclear if this is a Zed issue or Deno LSP issue... I posted here because I assume the Deno Language Server works with other tools, e..g VS Code seems to work fine with these files.

Reproduce

1. You can create a whole Fresh project using these instructions, or simply initialize a Deno project and create a file with brackets:

deno init
touch \[slug\].ts

2. Configure Deno with the extension and project settings described here
3. Open the project in Zed. Observe that when editing [slug].ts none of the language server features work.

Environment

Zed: v0.162.5 (Zed)
OS: macOS 15.1.0

For reference, just found a similar issue in Deno's repo: denoland/deno#26098
They confirmed it was an issue with the editor (Helix in this case).
Seems the solution in that case was to percent-encode the filenames.
