Bug Report: Plugin Fails with Chinese Paths Due to Encoding Issues​

Description
When using the plugin with file paths containing ​​Chinese characters​​, the plugin fails to call Pandoc correctly. The issue arises because the plugin passes Chinese paths to Pandoc, causing ​​encoding corruption​​ (e.g., garbled characters). Notably, Pandoc itself handles Chinese paths without errors when used independently. This indicates a plugin-specific encoding handling flaw.
