litherum has just created a new issue for https://github.com/w3c/csswg-drafts: == [css-values] ch units shouldn’t cause font downloads == Migrated from https://github.com/w3c/csswg-drafts/pull/3129 Right now, [Values and Units](https://drafts.csswg.org/css-values-4/#ch) says: > Equal to the used advance measure of the “0” (ZERO, U+0030) glyph in the font used to render it. It’s pretty unfortunate that ch units can cause fonts to download. WebKit doesn’t do this; it just uses the primary font, and if the primary font doesn’t support “0” then it uses that font’s .notdef glyph. No downloads necessary. https://trac.webkit.org/browser/webkit/trunk/Source/WebCore/platform/graphics/Font.cpp#L123 https://trac.webkit.org/browser/webkit/trunk/Source/WebCore/css/CSSPrimitiveValue.cpp#L661 In [this comment](https://github.com/w3c/csswg-drafts/pull/3129#issuecomment-423294483), @emilio says that Firefox does something similar.
