If font designers do not follow conventions, their glyph would be
trimmed out. Thus, CSS should follow JIS and other standards that font
vendors use.

be drawn: that's clearly outside the scope of CSS. What's being
is how the typical placement of punctuation within the glyph box affects
punctuation trimming behavior.
