IPA fonts provide totally four fonts - Mincho style and Gothic style and 
fixed width and proportional for each.
Our testcases  ONLY select fixed width Mincho and fixed width Gothic 
(two font types out of four) to ensure full width characters such as 
Kanji/Hiragana to be rendered with exactly 1em advance width and half 
width characters such as Alphabets to be rendered with 0.5em advance width.
Please note the source of the testcase says "font-family: "IPAMincho", 
"IPAGothic", "IPA明朝", "IPAゴシック";", this actually calls two font 
files, both are fixed width.
Please refer to the spec more detail.

Okay, I will update it with the combinations.

Okay, I will update it accordingly.

I will include this idea and will update with it.
