Re: [jlreq] Review the spacing property document to cover space collapsing between fullwidth and proportional punctuations (#340)

> key aspect is disambiguation of Roman chars from Roman (aka proportional or half-width) punctuation, 

As far as following current definition, all of A/B/AB has "so-called normal full-width" condition, so I believe such cases are taken up in that table.
For proportional Japanese fonts, user agents shall take care of how much spacing is in glyph, and nothing could be taken account in collapsing rules. These are the same as non-proportional ones, but are just a matter on width of spacing included like 0 to 0.5 em for proportional against exactly 0.5em for non-proportional.
