Use case or problem
Hello Obsidian team,
I would like to report an issue regarding the rendering of CJK punctuation variation selectors (IVS) on the Obsidian Android app.
When using Chinese full-width quotation marks with variation selectors, such as:
-
“︁(U+201C + U+FE01) -
”︁(U+201D + U+FE01) -
‘︁(U+2018 + U+FE01) -
’︁(U+2019 + U+FE01)
the intended glyph variants are not displayed. In contrast, these sequences render correctly in other native Android text editors. Emoji variation selectors (FE0F / FE0E) still work correctly in Obsidian, indicating that the issue is specific to CJK IVS characters.
It seems that the WebView rendering path currently used in the app ignores IVS for certain punctuation characters, causing fallback to the default glyph.
Supporting CJK IVS in the Android app would allow users to have typographically correct Chinese punctuation, which is important for academic, professional, or precise note-taking contexts. A possible solution could be enabling proper IVS handling in WebView or allowing users to select a font that fully supports these glyph variants without being overridden by fallback.
This can be implemented by default in the default system font and some Android text boxes
Thank you for considering this enhancement.
