That doesn't necessarily answer my question, unless the font used to display those two characters is different in "emacs -Q" and in your customized session. If both use the same font, please try forcing Emacs to use some other font, perhaps one that is more wide-spread on GNU/Linux systems, and see if that changes anything. If that doesn't help, then the next question is: is this problem specific to these two characters, or is it more general? If the latter, I suspect the shaping engine used in your case is the culprit, so perhaps upgrade your libotf, libm17n-flt, and m17n-db packages. If you already have the latest versions of these, it would be time to ask Handa-san to chime in and look into this.
