Fix InvalidCharacterError

in Vite

Solution

InvalidCharacterError in vite often stems from unexpected or malformed characters (like control characters or unescaped Unicode) in your JavaScript, CSS, or imported assets, especially within `sourceMappingURL` directives or string literals. To fix it, identify the offending file and line using the browser console, then either remove the problematic characters or properly escape them using techniques like unicode escape sequences or by sanitizing the data during build process if the file comes from external source. Consider adding a plugin to your build process to automatically sanitize your files.
