This is the first font I ever made since I obtained its first debut on January 25th, 2019. As you might have guessed, this is Computer System 5x20, but only the font you see has its size of 48 pixels.
I have also used Combining Diacritical Marks for this type of unicode only because not only it works with combining a diacritical mark into this letter, it can also be used for international/worldwide purposes.
There are some major changes to the new LCD font before the re-arrival of the new JR E230 series. Currently, this new LCD font was only viewable in all stations excluding a 2018 JR E234 bullet train (or Shinkansen).
But this was just introduced in June 20th, 2018, and is viewable to the public.
