So, you got a mysterious compile error and if you're lucky, your compiler will
at least show you
ZWNBSP instead of just a space.
Chances are your file got encoded in
UTF-8 BOM instead of just
UTF-8, and your compiler
is choking on the Byte order mark.
To fix it, convert the file to
UTF-8 without BOM.
This has happened to me several times over my career in various languages and has cost me hours of senseless debugging. Maybe you're lucky enough to find this post quickly when it happened to you.
As an example, here's an error message from the Clojure compiler:
Syntax error compiling at (somefile.clj:3:1) Unable to resolve symbol: ZWNBSP in this context
Convert to UTF-8 without BOM
- Save the file.
You should see your current encoding in the lower right status line.
Click on it and choose
Configure IntelliJ to prevent this
Settings -> Editor -> File Encodings
Create UTF-8 filesto wih NO BOM
