Comment (by ErlendH):

 This patch uses the following symbols:

 - U+201B SINGLE HIGH-REVERSED-9 QUOTATION MARK
 - U+2019 RIGHT SINGLE QUOTATION MARK

 Shouldn't the first one be U+2018 LEFT SINGLE QUOTATION MARK to match the
 right quotation mark?
 Right now it looks really unbalanced with the fonts I tested. Is this
 intentional?

 Here's a screenshot, using Microsoft's Source Code Pro font:
