Can Plex support all characters of GB18030 character set?

[Seanxy]

We want to add Plex font in our product to support Simplified Chinese, and would like to know if the latest version of this font supports the characters in the GB18030 character set? According to the GB18030-2022 standard, which level does it support, Level 1, Level 2, or Level 3? That is, does it support all characters in GB18030 character set or only some of them?

IBM Plex Sans Chinese SC supports GB18030-2022 Level 2.

@Skr-ZERO thanks for your reply! Is there any plan to support the characters of GB18030-2022 Level 3 in IBM Plex? If there is such a plan, may you share the approximate time when IBM Plex supports these characters?

To support all the characters of GB 18030-2022 Level 3, A MOUNTAIN of glyphs need to be added, which will take many years and A GREAT DEAL of effort.

I think this font family has no plan to reach this goal.

@lxgw Thanks for your information!

Since I'm planning to use this font, I conducted a test on Chinese characters (GB18030-2022) based on IBM Plex Sans Chinese SC v1.0 and found that there were Level 1 characters without glyph shapes (for example, the character "︙" (U+FE19)). I am not sure if this can be considered a font bug, just reporting it here.
