Description:
CJK Ideograph Rendering Issue on LibreOffice Impress All Platforms(All Linux, Windows, Mac OSX etc). 



Now, I use Noto CJK fonts ( https://www.google.com/get/noto/help/cjk/ ) on LibreOffice Impress.

Because, I'm writting  and checking about Ideographs Difference between Glyph in Chinese, Japanese, Korean, using Noto CJK Fonts.

Noto CJK Fonts(Korean, Japanese, Traditional Chinese, Simplified Chinese) includes CJK Unified Ideograph glyphs. There are expressed CJK Unified Ideographs in each languages(Korean, Japanese, Traditional Chinese, Simplified Chinese).
Korean, Japanese, Traditional Chinese, Simplified Chinese are different language, but There are use Ideographs(漢字/汉字,reads Korean: 한자/hanja, Japanaese: かんじ/kanji, Chinese: hànzì).

I write one Ideograph character 漢 (U+6F22) on Impress.
Also write same thing and changed Fonts, First, Noto Sans CJK JP(Japanese), Second, Noto Sans CJK KR(Korean), Last, Noto Sans CJK TC(Traditional Chinese). Last one next one is another Ideograph character 汉(U+6C49) [Noto Sans CJK SC(Simplified Chinese)]

漢 (U+6F22) is Same Code point, but Difference between Glyph in Chinese, Japanese, Korean.
But, All platform's LibreOffice Impress shows only same glyph(I'm Korean users, I think, Maybe LibreOffice Impress follows Korean locale.)

For the first time, I was wondering if there was a problem with KDE's CJK Ideograph font rendering. (Because I'm KDE Plasma & openSUSE Linux User).

Last Sunday, I met KDE e.V members in Korea and KDE board member, I checked KDE's CJK Ideograph font rendering.
KDE's presentation application, I opened odp file on Calligra Stage. But, It's correctly shown CJK Ideograph fonts.

And I checked both KDE character map(kcharselect) & GNOME character map(gucharmap). It properly represent each font, I checked. (Noto Sans CJK JP[Japanese], Noto Sans CJK KR[Korean], Noto Sans CJK TC[Traditional Chinese], Noto Sans CJK SC[Simplified Chinese])

Also I checked MS Office both MacOSX & Windows. It shows correctly.

But, I checked LibreOffice Impress Linux, Windows, MacOSX, I found the CJK Ideograph Rendering Issue.




Steps to Reproduce:
1. Enter the same letter, '漢' (U+6F22) 3 times
2. Replace three letters with different fonts. In the following order, First, Noto Sans CJK JP(Japanese), Second, Noto Sans CJK KR(Korean), Last, Noto Sans CJK TC(Traditional Chinese). 
3. Checked it 

Actual Results:
Depending on your language locale setting
I'm Korean user and setting Korean locale on desktop, It shows Same Korean font glyphs.

Expected Results:
Checked the character 漢 (U+6F22) on The Unicode Standard, Version 11.0 CJK Unified Ideographs Code Point Chart Range: 4E00–9FEF
https://www.unicode.org/charts/PDF/U4E00.pdf

It shown Ideograph difference between Glyph in Chinese, Japanese, Korean, Vietnamese.


Reproducible: Always


User Profile Reset: No



Additional Info:
Noto Sans CJK and Noto Serif CJK comprehensively cover Simplified Chinese, Traditional Chinese, Japanese, and Korean in a unified font family. This includes the full coverage of CJK Ideographs with variation support for 4 regions, Kangxi radicals, Japanese Kana, Korean Hangul, and other CJK symbols and letters in the Basic Multilingual Plane of Unicode. 
1. Noto Sans CJK KR (Korean)
2. Noto Sans CJK JP (Japanese)

Comment 11 Jan-Marek Glogowski 2018-11-20 07:42:23 UTC
As far as I can tell the problem is your formatting of the characters in Impress and not a LibreOffice problem.

I guess you're talking about Impress slide three.

If you check the language of the single characters, all are set to "Korean (RoK)". You can check this by selecting the single character and then Format -> Character… Asian Text Font -> Language.

The reason is that LibreOffice knows the language of the text and that the font doesn't have the glyph (= character) in your selected language. So it automatically looks for the correct glyph in the text language in other fonts LibreOffice finds on the system to show the correct character in the selected language, regardless of the selected font.

If I change the language of a first character to Japanese, like the font indicates, the glyph actually changes. I don't see a difference between the KR and TC variants, if I set the third character to "Chinese (traditional)", but probably I'm missing a font here.

I just tested with my master build which is almost your 6.2 beta, just a bit newer.

Please reopen the bug, if this is still broken for you.

LibreOffice's Noto Sans CJK font rendering characters example odp file

I uploaded the difference of Ideographs[漢字, Chinese Characters] Example odp file.

It compares to 

That is the ODP file, comparing Noto Sans CJK Font(TC[Traditional Chinese], SC[Simplified Chinese], JP[Japanese], and KR[Korean]) with the Code Chart PDF file of the Unicode Consortium.

on Microsoft Office, The glyph in the Selected Noto sans CJK font(TC[Traditional Chinese], SC[Simplified Chinese], JP[Japanese], and KR[Korean]) are displayed correctly. But LibreOffice don't look right, It follows Language settings on LibreOffice.

When Checked the Spelling Check, It only shows Korean Hanja

When It Checked on the Spelling Check on LibreOffice, It only shows Korean Hanja(한자/漢字) style Ideopgraphs.
LibreOffice don't look right, It follows Spelling Check settings on LibreOffice.

If you get off the spelling check option, The glyph in the Selected Noto sans CJK font(TC[Traditional Chinese], SC[Simplified Chinese], JP[Japanese], and KR[Korean]) are displayed correctly on LibreOffice.

You can't confirm your own bugs. Moving it back to UNCONFIRMED until someone
else confirms it.
Comment 17 DaeHyun Sung 2019-06-01 00:53:09 UTC
LibreOffice Impress CJK Input Test on MacOSX(10.14 Mojave)
Using Default MacOSX Input Method Engine(IME)[Chinese(Traditional, Simplified), Japanese, Korean], I found Japanese Input error on LibreOffice Impress.

compare with Version 6.2.3.2 and Version 6.3.0.0.alpha1+
(Build ID: 1376bb3e44c4b9eb15cf788df04f7cc0bba8cb09).

In CJK(Chinese,Japanese, Korean) Input test, Japanese Input kanji word rendering is error , unlike Chinese on LibreOffice Impress.
