+%
+% Please don't use IPAex family fonts like IPAexMincho and/or IPAexGothic.
+% Because some characters are converted into Kangxi radical.
+% Example:
+% 一 (U+4E00) -&gt; ⼀ (U+2F00),
+% 人 (U+4EBA) -&gt; ⼈ (U+2F08),
+% 非 (U+975E) -&gt; ⾮ (U+2FAE),
+% 高 (U+9AD8) -&gt; ⾼ (U+2FBC) etc...
+% This conversion is not problem for printing, but
+% is problem for searching pdf and converting pdf into text.
