The proposed SC should cover these scenarios too, or at the very > least mention them. The font bullet was removed from the current Adapting Text SC [1] in part due to internalization concerns. Please check the Adapting Text Open Issues [2] as well as the Adapting text user to content requirements table [3]. Since we don't have the font bullet anymore, I wanted to verify with Wayne that the spacing metrics in the SC are adequate for when a large font-family is selected and/or increased spacing is applied to text for some layouts. The SC text [1] currently reads: <quote> If the technologies being used by the author allow users to override the author-supplied values for the appearance of text (with the exception of images of text and closed/open captions), no loss of essential content or functionality occurs when the following are overridden: * line spacing (leading) to at least 1.5 * letter spacing (tracking) to at least 0.12 em * word spacing to at least 0.16 em Editor's note: The Working Group seeks to to include overriding text color, background color, and font-family as part of this SC, but is not yet able to identify a way to do so that is sufficiently testable. </quote> Do you think we need an additional editor's note regarding the spacing metrics impact on internationalization, even though we don't have a font bullet? If so, can you suggest text for it? Thank you.
