Enabling ss02 (arrow ligatures) without also enabling ss01 makes it impossible to write <=

It appears that enabling ss02 replaces the <= characters with a double-stroked arrow. In almost all programming languages this character combination is supposed to represent "less than or equal to", so this seems problematic. The only way to resolve this problem while still having access to the other arrow ligatures is to enable ss01 as well.

Oh, I've noticed that <= renders as expected if-and-only-if it is surrounded by whitespace on each side. This is strange.
