Error : File Load Some bytes have been replaced with the Unicode substitution character while loading file, ERROR: Unable to create child process

 

 

I started to get this error after switching on (for test purposes) the new setting "Beta: Use Unicode UTF-8 for worldwide language support" in the recent Windows 10 Spring 2018 update.

The message would then appear for every file that has non-ascii characters (German Umlauts mostly in my case) and had not been stored as UTF8 before.

Short-time fix: Revert the setting to not use UTF-8 as the "Current language for non-unicode programs", but use a language with the special characters that are used in the source files.

Long-time fix: Convert all your soure files to UTF-8.
