I dumped UnDotum.ttf with ttx(fonttools) as xml format.
And I checked the xml format of UnDotum font in UnDotum.ttx.

In the font hmtx table((horizontal metrics) table),
And find something which maybe relative with this problem:
In font UnDotum:
    <mtx name="uni11AA" width="0" lsb="-848"/>
    <mtx name="uni11AB" width="0" lsb="-828"/>
    <mtx name="uni11AC" width="0" lsb="-812"/>

And in font WenQuanYi:
    <mtx name="uni11A9" width="1024" lsb="157"/>
    <mtx name="uni11AB" width="1024" lsb="251"/>
    <mtx name="uni11AE" width="1024" lsb="245"/>
