Sorry for the delay.
I am uploading screenshots I took of each of the English and Japanese environments.
In the attached image, the font specification is correctly reflected in the English environment, but in the Japanese environment, even though the Stencil font is clearly specified, some other font (default font?) is displayed.
You will also notice that other identical font parts are not as specified in the Japanese environment.
However, if a font such as MS Mincho is specified, it will be displayed correctly.
My guess is that ASCII-only fonts are not displayed correctly.
