I’m running Linux but I gave it a quick run and like I mentioned you should have looked at row 142 and played around with it a bit. There are some invisible chars in the file → Unicode Character 'ZERO WIDTH SPACE' (U+200B)
If you use Intellij you can take a look at https://plugins.jetbrains.com/plugin/7448-zero-width-characters-locator
In Vi this is visible by default
replace the whole block with the one I post here.
