Now that I turned off zooming in my browser (i. e. now I browse with 100% zoom), I find all the icons in this category unreadable at 20px... YLSS (talk) 22:37, 29 May 2014 (UTC)[reply]
Yes, this needs work. But what matters here, more than the exact glyphforms, is the basic concept: Custom created glyphs mannually “hinted” to match our (most usual) 20 px use — instead of relying on rendered SVGs calling fonts resident at the users or at the server. -- Tuválkin✉18:09, 30 May 2014 (UTC)[reply]
I totally agree! If anyone will ever come around with this, I would prefer shapes similar to the middle "1" and right "2" in the top image, as well as the placement as tight to the image border as possible: that leaves more space when labelling a station.
