I think you need to change the glyphs some more...

[Marcus98T]

I know you started with Genne Gothic as a base, but unfortunately I do not believe that the font has the full Kangxi glyphs. I also want to upstream some changes from SHS v2.001. Even though it is for 源樣黑體, the table also have Source Han Sans CID.

The 牙 radical has to follow that of 源樣黑體, not the KR form. I don't have the time to find the Unicode number and CID number for Source Han Sans.
Affected characters: "牙冴訝呀邪鴉雅芽穿". You need to dig into the hidden glyphs of Source Han Sans in order to get those glyphs.

The characters with 呈 need to be changed also. Affected characters are "呈程浧珵桯鋥聖檉".
Use the TW form: "呈程聖"
Use the JP form: "浧珵桯鋥檉"

Also the 青/靑, 清/淸, need to unify to the latter. Same with U+7BC0 節; need to use U+FA56 (Update: It's at SHS v2 CID: 58950) for the main codepoint. Details here: #22

More characters I want to switch here, should apply to this font also:
ButTaiwan/genyog-font#21
ButTaiwan/genyo-font#9

Add the U+32FF ㋿ SQUARE ERA NAME REIWA from Source Han Sans v2.001 as well.

Given the computational nature of Glow Sans, manual glyph fixes are not under consideration, and it is a shame that, font build for Glow Sans has ignored the original CID of Source Han Sans, which makes such problems even harder to fix, unless I have enough time on this project to rewrite the building scripts.

Adding support for other Unicode blocks is working in process. Hopefully, the Reiwa glyph (U+32FF ㋿) will be included in future versions.

If so, I suppose the CID for Glow Sans (Genne Gothic) was based on Source Han Sans v1.004, and then the CID for v2.001 is all changed. This will take quite a lot of time and work to pinpoint where the glyphs exactly are. I may not have the time to pinpoint every single glyph that needs changing, but I might use the Source Han Sans v2.001 CID as a starting point, followed by the respective Unicode codepoint (or CID) of Glow Sans to change to, if that's what you want.

[celestialphineas]

Full v2.001 CID correspondence for a classical orthography is certainly welcomed. I would appreciate it if someone would have such data.

Unfortunately as you know, v2 of SHS removes extra JP glyphs like 惦 because of the demand for HK glyphs. So I can only at most partially take from v2 for some glyph fixes, as mentioned in my top comment.

Unfortunately, I don't have so much time to do an exact list as you wish, this can take up to a month for me to furnish such a desired list, but the hint is to look within these ranges of CIDs:

• 58855 to 58973
• 61800 to 61853
• 61896 to 63107 (the majority where the hidden Kangxi glyphs are and most are mapped to the KR version of SHS, but not all)

[Marcus98T]

Change these glyphs to the CID of Source Han Sans v2.002:

• 欤 to 62445
• 婦 to 62216
• 寧 to 62232
• 呈 to 62157
• 程 to 62572
• 聖 to SHS TC form
• 篠 to SHS JP form
• 肏 to SHS TC form
• 条 to 62396
• 空 to 62578 (optional, not required)
• 控 to 62337 (optional, not required)
• 腔 to 62689 (optional, not required)
• 与 to 62068
• 主 to 62073
• 住 to 62078
• 拄 to SHS JP form
• 往 to 62276
• 注 to 62456
• 駐 to 63041
• 柱 to 62404
• 註 to SHS JP form
• 免 to 58914 (same codepoint as U+FA32)
• 悗 to 62288
• 晚 to 62368
• 兔 to 61806
• 冤 to SHS JP form
• 起 to 62827

If I said SHS JP form, for example, which means take from version 2.002 of the Japanese version of Source Han Sans. I don't know where the CID is, but the desired form is encoded into the specific font by default.

More to come soon.
