Common NLS problem and possible causes

A common NLS problem with potential solutions.

Why do I see a square box or ??? (question marks) in the SDK components?

This effect is caused mainly because Java™ is not able to find the correct font file to display the character. If a Korean character should be displayed, the system should be using the Korean locale, so that Java can take the correct font file. If you are seeing boxes or queries, check the following items:

For Swing components:

1. Check your locale with locale
2. To change the locale, export LANG=zh_TW (for example)
3. If you know which font you have used in your application, such as serif, try to get the corresponding physical font by looking in the fontpath. If the font file is missing, try adding it there.
