SharePoint whitespaces prevent :first-letter CSS from functioning properly

I have a CSS rule that makes the first letter of my titles blue, something like this : h1:first-letter { color: blue; }

This works fine, except for the fact that SharePoint sometimes adds "extra" whitespaces in front of my title strings. The character is ​.

Is there a way to fix this, maybe with jQuery that would lookup the string and delete it ?
