EVALUATION This sounds like the font doesn't have all the glyphs. ###@###.### 2001-12-19 Need to check if the simplified Chinese fonts chosen for the Windows L&F have Latin-1 glyphs. If not, Swing needs to relook at it's approach to choosing fonts for native L&F. ###@###.### 2001-12-19 Apparently the WindowsL&F is picking Tahoma, which is not a composite font. ###@###.### 2002-02-06 To disable swing from using the desktop fonts you can set the system property swing.useSystemFontSettings=false, which will mean we then revert to the composite fonts and all should be well. Our options for this are: 1. wait till there is api to create composite fonts 2. turn off picking up desktop fonts For the time being we are going to stick with option 1. If this becomes a big problem (lots of customer votes), we will go with option 2. ###@###.### 2002-02-06 Name: nl37777 Date: 03/22/2002 JDC comments also report the same problem on Windows2000sp2(Japanese). Tahoma does not have any CJK glyphs. Asking application developers or end users to use a system property is not an acceptable solution. Text display in the local language must work right out of the box for all supported writing systems. ====================================================================== By popular demand we will be fixing this in hopper. As there is currently no API to create a composite font we will no longer pick up the windows fonts names in 1.4.1, rather we will just pick up the font sizes. In 1.5 we should have the ability to create composite fonts, at which point we can switch back to using the font name windows specifies. ###@###.### 2002-03-22 The fix consists of two parts: . SunGraphicsEnvironment now has the method fontSupportsDefaultEncoding, which returns true if the font supports the encoding corresponding to the file encoding property. . WindowsLookAndFeel will now use this property to determine if it should use the font returned from the desktop. For systems, like Chinese 2000, this will return false and Swing will fallback to Dialog with the font size coming from the desktop. ###@###.### 2002-04-19

WORK AROUND Turn off picking up of system fonts by setting the system property 'swing.useSystemFontSettings' to false. ###@###.### 2002-02-06
