When using an SVG font in HTML, if the SVG font doesn't contain a glyph that is in the text, font substitution doesn't work. The glyph defined by <missing-glyph /> is rendered instead of an alternate from another font that does define the glyph. This is using WebKit nightly build 30662.
Created attachment 19448 [details] test file that reproduces bugs # 17541 and 17608 visually. This file demonstrates bugs #17541 and #17608 visually.

Awesome. :)
Created attachment 95893 [details] Slightly modified testcase To make the testcase work in Opera as well, make it a XHTML document. The bug seems gone in trunk though, I'll create a testcase for the use within DRT soon.
Fixed in r89233.
