Subject: PROBLEMS WITH JAVA 2 PLATFORM INTERNATIOLISATION

The problems report to Sun Microsystems.
 
 
 
 
Dear sirs!
 
 
We are porting our programs from jdk1.x.x to Java 2 Platform.
The main difficultings are internalisation and using national characters.
The problem consists of the two parts:
1. On Solaris 2.7 in light-weight components method Graphics.drawString(String)
   does not draw Russian chars (native components seam to be okey after some changes
   in font.properties or font.properties.ru) as long as we use HDS View Station,
   but almost everything looks like the right thing on main console, pluged in
   system block of x86 computer.
2. The more important at the moment is Russification of Java 2 in Win95/98:
   We tried jdk1.2beta jdk1.2 jdk1.2.1 jre1.2.2, the problem persists at the
   same form at four cases enumerated.
   After instalation, no russian fonts avalible in java, when fonts from java/lib/fonts
   instaled (we have Lucida family fonts in java/lib/fonts) situation changes dramaticaly:
   for example if we write dialog1=Cucida Regular, RUSSIAN_CHARSET (or so on)
   to the font.properties or font.properties.ru java writes: Lucida Regular font in
   font.properties not found ... , but Russian characters appeares in our window,
   both in native and light-waight components with wrong metrics.
   Lines of text lookes 3 higher - spaces above and belaw symbolse are filled with nothing
   eache approximately as high as the letters are!
   Changing dialog1 and dialog2, one could see that java does not use them as default
   substitution for wrong font of dialog0, so this way we can not reveal which font is realy
   used at this case, even more Lucida Regulear seam not to have Russian page at all in jre1.2.2,
   but it effects the same way as in case of Russian fonts Cucida Regular.
   Other applications (Word,Notepad e.t.c. do not detect Lucida fonts, provided with java
   inspite of thease fonts installed the right way via fontmanager and detected by Explorer in
   windows/fonts directory)
 

 Applying a simple example program, I used to investigation of fonts' problem.
 (need to compile it with -J-Dfile.encoding=8859_5 to preserve russian chars in compiled
  class or use \uXXXX unicode assignment in drawString and setText methods)
