Files with unicode in a non-last component breaks Glint

[NullVoxPopuli]

in app/templates/index.gts

I import './page' (another .gts file), and get these errors:

app/templates/index.gts:8:45 - error TS2306: File '<..>/app/templates/page.ts' is not a module.

8 import { Article, InternalLink, Link } from './page';
                                              ~~~~~~~~

app/templates/index.gts:8:45 - error TS5012: Cannot read file '<..>/app/templates/page.ts': 
  Internal error: missing location info for template.

8 import { Article, InternalLink, Link } from './page';
                                              ~~~~~~~~

A Glint internal error:

This could be due to unicode remapping from content-tag, as described here:

• https://github.com/embroider-build/content-tag/issues/45

Which I 100% confirm via deleting a "🎉" (or by moving the component-containing :tada: to the end of the file).

I suspect this also needs to be fixed on main as well.
