[GitHub] [netbeans] rkeen-siemens opened a new issue, #4818: Some Unicode characters display as \u escapes

[GitBox <gi...@apache.org>]

rkeen-siemens opened a new issue, #4818:
URL: https://github.com/apache/netbeans/issues/4818

   ### Apache NetBeans version
   
   Apache NetBeans 15
   
   ### What happened
   
   Some Unicode characters display as \u escapes in the property sheet. I would expect that if they can be rendered (as you can see when editing the value in the property sheet) that the actual character glyph would be rendered rather than the textual escape.
   
   ### How to reproduce
   
   1. Create a new JForm Java application
   2. Add a component with a text property (e.g. a `JLabel`)
   3. Set the text property to something containing a Unicode character that is not supported directly by the font (e.g. `𝑣₁=∣𝘝∣/ω ⏰`)
   4. Move the focus to another property
   
   You'll now see the text with the Unicode characters escaped. The actual behavior will depend on the current UI font you are using, but on Linux the string above appears as `\ud835\udc63₁=∣\ud835\ude1d∣/ω ⏰`
   
   ### Did this work correctly in an earlier version?
   
   No / Don't know
   
   ### Operating System
   
   Windows 10 Pro, CentOS 7.6 with Gnome 3
   
   ### JDK
   
   Java 17.0.4.1
   
   ### Apache NetBeans packaging
   
   Apache NetBeans provided installer
   
   ### Anything else
   
   The renderer attempts to avoid showing undisplayable characters and converts them to their unicode escapes using [RendererFactory.makeDisplayable](https://github.com/apache/netbeans/blob/81fae58229c39adbe4f5b3b371a7087562e781bb/platform/openide.explorer/src/org/openide/explorer/propertysheet/RendererFactory.java#L475). However, it uses [Font.canDisplay(char)](https://docs.oracle.com/en/java/javase/17/docs/api/java.desktop/java/awt/Font.html#canDisplay(char)) which cannot handle supplementary characters. It should use [Font.canDisplay(int)](https://docs.oracle.com/en/java/javase/17/docs/api/java.desktop/java/awt/Font.html#canDisplay(int)) and provide the character as a Unicode code point.
