Fixed issue with the bold italic version of mononoki font is detected as a separate font

[Case3y]

When I use windows terminal, I found that the blod italic version of mononoki font is detected as a separate font. I can choose mononoki BoldItalic. And there was no blod italic version when I choose mononoki font in Git Bash.

I intall the ttf font on my Windows system.

The number of fonts identified in the settings is correct !

But it is wrong in some software !

I solved the problem using this method proposed in #49， I delete the "Preferred Name" and "Preferred Styles"

What worked for me on Windows 7 SP1 is:

• Open mononoki-BoldItalic.ttf with FontForge.

• Choose "Element" menu -> "Font Info".

• Choose "TTF Names" tab in the appeared "Font Information" window, and remove the "Preferred Styles" entry with its right-click menu.

• Re-export the TTF via "File" menu -> "Generate Fonts".

It seems Windows is extraordinarily picky on many font properties.
