@0xda157, the editorconfig from commit 7fc0a87 ("stylix: add editorconfig (#945)") is causing weird problems:

$ nix build .#checks.x86_64-linux.pre-commit
error: Cannot build '/nix/store/1zdrv25vilgpcvb83c8r1icvqq7a88zm-pre-commit-run.drv'.
       Reason: builder failed with exit code 1.

The following suboptimal workaround resolves the failure:

diff --git a/.editorconfig b/.editorconfig
index cef70f21..613d5c37 100644
--- a/.editorconfig
+++ b/.editorconfig
@@ -6,7 +6,6 @@ end_of_line = lf
 indent_style = space
 insert_final_newline = true
 trim_trailing_whitespace = true
-charset = utf-8

 [*.{diff,patch}]
 end_of_line = unset

What needs to be done to properly resolve this issue:

$ file --mime modules/{fcitx5/highlight,qt/kvantum}.svg.mustache
modules/fcitx5/highlight.svg.mustache: image/svg+xml; charset=us-ascii
modules/qt/kvantum.svg.mustache:       image/svg+xml; charset=us-ascii

Is this maybe a false positive?
