Report of characters that may need new glyphs for HK

[tamcy]

The following HK characters cannot share glyphs with other regions. A new glyph would probably be necessary, but I didn't go through all CIDs so I'm not sure if any unmapped glyph could be used. That's why I open a new issue here.

[Edit: removed 巟 & 慌 as they're reported before]

A. 𦐇-related characters

Character	Current region	Remarks
U+6428 搨	TW	Top-right component is different
U+69BB 榻	TW	Top-right component is different
U+6BFE 毾	TW	Top-right component is different

(I do have doubt about why this form was chosen, and will take my query to OCGIO-CLIAC when I have time)

B. Others

Character	Current region	Remarks
U+38FA 㣺	CN	I think its height should look like the JP glyph - not 100% sure though
U+53B4 厴	TW	The “bottom meat” component ⺼ is different, can‘t share with TW; 犬 is different so can't map to JP
U+5EE8 廨	JP	The first dot of 广 is not a vertical stroke
U+64DB 擛	JP	The grass radical 艹 is different, can’t share with JP
U+6A07 樇	CN	Top-right component: CN uses 夂 while HK uses 攵
U+6F16 漖	CN	Unlike CN, the 子 doesn’t protrudes the 𠂇 component in HK (ref: U+6559 教, looks subtle to me tough)
U+95B9 閹	JP	Last stroke of 大 is curved towards inside
U+9B2F 鬯	JP	The bottom component 匕 is different, can’t use JP glyph (Ref: U+9B31 鬱)

[tamcy]

Character	Current region	Remarks
U+69A7 榧	JP	The 匚 component is different (this can actually be considered a design difference, just that it is not consistent with other characters)
U+7DFB 緻	CN	Rightmost component: CN uses攵while HK uses 夂 (ref. U+81F4 致)

[tamcy]

U+6BCC 毌: Currently using CN glyph.

毌 is the component used in 貫, 實 etc. The HK Reference Glyph document states that the TW form is the same as the HK form dispite the different at the bottom-right corner. So TW is a more suitable mapping if no new glyph is to be introduced.

[tamcy]

U+8943 襃: The component left to 呆 is same as that in 印, which consists of 4 srokes according to TW and HK conventions. The vertical stroke and the rising stroke are disconnected. So similar to U+88E6 裦 and U+890E 褎, a new glyph would be required for U+8943 襃.

[tamcy]

U+465B 䙛: The CN glyph was fixed by changing the middle component on the right from 厶 to 口, causing a side effect that it's no longer sharable with HK.

U+9834 頴: Top-left component is different, can't use JP glyph.

U+72C5 狅: The HK glyph isn't correct. But TW glyph is probably wrong too, as it currently looks the same as U+72C2 狂.

[LiliCharlie]

Also, whenever 女 is a left radical, as in 好 and numerous other characters, the strokes ㇒ piě and ㇀ tí for the HK glyphs should neither intersect (as in the current Source Han Sans HK font and in the TW standard), nor meet at their exact ends (as in the CN standard). Rather, ㇀ should touch ㇒ near its upper end. (Intersecting ㇒ and ㇐ héng are correct when there is no other component to the right of 女, as in 女, 妻, and for the upper and the lower right components of 姦, as opposed to the character's lower left component.)

[kenlunde]

@LiliCharlie Unifiying the HK form of the left-side 女 component with the TW form was an intentional design decision, and therefore a non-issue. For comparison, Apple's Pan-Chinese PingFang family went to an extreme whereby the CN form of this component is used in its SC, TC, and HK fonts.

[LiliCharlie]

Unlike all other CJK locales the 丱 component in HK-style 關 and 聯 has ㇑ instead of ㇓.

[kenlunde]

@LiliCharlie You'll need to provide a much clearer explanation, because there is no HK-specific glyph for either U+95DC 關 or U+806F 聯. The former has only JP (shared by KR) and CN (shared by TW and HK) glyphs, and the latter has JP (shared by KR), CN, and TW (shared by HK) glyphs.

The image below shows their JP, KR, CN, TW, and HK forms:

In the HKSCS Reference Font "華康標準宋體"="DFSongStd" available from https://www.ogcio.gov.hk/en/our_work/business/tech_promotion/ccli/download_area/font_and_software.html the characters look like this:

The 丱 component has a ㇑ where the other locales have a ㇓.

[tamcy]

@LiliCharlie Note that Source Han Sans HK follows the "Reference Glyphs for Chinese Computer Systems in Hong Kong" released by OGCIO in 2017, which can be downloaded here. The document is more recent than the font you mentioned, which was released in around 2007.

Here's an excerpt from the document. The non-vertical form is adopted for the second stroke of the 丱 component.

[LiliCharlie]

@tamcy Oh, I see. And the same thing seems to have happened to the kai-style glyphs representing 關 and 聯.
Are the fonts the 2017 "Reference Glyphs for Chinese Computer Systems in Hong Kong" document was produced with available for purchase or otherwise?

[tamcy]

@LiliCharlie So far no downladable/purchasable font product was released alongside the Reference Glyph document.

[LiliCharlie]

@tamcy That's a pity. My pdf analysing tool reports that fonts called "華康香港新標準宋體(P)", "DFHKNewStdSong-W3-HKSCSP-U", "DFHKNewStdKai-W5-HKSCSP-U", and "華康香港新標準楷書(P)" are among the ones used to produce the document. The people of DynaComware Corp. should know more.

[LiliCharlie]

I think I've found the two fonts at https://www.dynacw.com.hk/en/product/product_download_detail.aspx?sid=2588 and https://www.dynacw.com.hk/en/product/product_download_detail.aspx?sid=2589 (replace /en/ with /zh/ to change the language to Chinese).

HK and TW glyph additions from this issue are now reflected in the table in Issue #206.

[tamcy]

Thanks! As the design of 狅 is different for TW and HK (the middle horizontal stroke is narrower than the bottom one for TW, for HK the middle one is the widest), I think a new HK glyph will also be needed in addition to fixing the current TW one?

[kenlunde]

Right. I modified the table in Issues #204 and #206 accordingly.
