Nice.

I like it, JingYo, so much that I cloned it to investigate it, as I wanted to help you correct a flaw that I thought I saw, and to my amusement, it is simply a part of the character of the font that actually works quite well, it just looks a little strange when the font is presented as an alphabet.  The trick you use though, allowing a leading rounded bead to the left of the left line border, may cause some printing issues when one of those characters is the first in a line that has no paragraph indent (it might extend beyond the printable area border on the left).

That said, I like it and most software programs will accomodate this type of thing, especially in this day of swashy everything.  I think the primary issue is that Fontstruct itself has this display issue. 

So, what I mean is... Cool, I like it.  I'm putting it in the Font-Journal.
