Subject: Add support for 'zero' (slashed zero) feature
X-Git-Tag: bedstead-3.261~13
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~bjharris/git?a=commitdiff_plain;h=fa88f696c70fc62212f64d24e6d7b212ae4d5296;p=bedstead.git

Add support for 'zero' (slashed zero) feature

This re-uses the old Oslash glyph I drew that had the slash entirely
inside the O.  I've seen something similar on simulations of old
character generators, though I'm not sure I've seen any actual character
generators using this shape.
