• is this scope of esbuild? or this could be done in the one who will use the esbuild?
• i did some string replace to my code str.replace(/[^\0-~]/g, ' ')

Thanks for the report. This is a bug in esbuild. It looks like I need to handle these unusual whitespace characters as whitespace. In the meantime you should be able to do something like str.replace(/[^\S\r\n]/g,' ').
