Some character samples in Appendix A tables are in full-width character

(Not adding errata label, rather rising a question to editors)
In Appendix A tables, characters are shown in table as samples for rows. Some row points UCS code points in U+00XX (half width signs) but have full-width equivalent for sample, like '（' (U+FF08) in third row of Appendix A.1 cl-01 for U+0028.
Do we need to show actual representatives for UCS codepoint, or it's fine since these are just showing shape?

Note, this is the same for 2nd WG Note at 3rd April 2012.

Closing this, discussed during 2019/May F2F, we agreed we can left them as is, just to show samples of shape.
