Copy/source mode in code macro using incorrect character for a space in Chrome

Using the copy/source feature of the code macro, where one is able to copy the content of the code block, doesn't work as expected in Chrome. Space characters (32) are displayed as, and therefore copied as, (160) - a non-breaking space.

This appears to be due to the use of

 

when rendering spaces in the code blocks. Chrome now faithfully renders

 

using the correct unicode character 160.

This can cause interesting problems when trying to copy a code block to a terminal or other application.
