Charset and Custom Item

kosta

Hello BIRT community,

I have created custom item that prints German Text. In the developer enviroment it works fine. The UTF-8 text is shown like it should be. The custom item is used in a rptdesign file.

When the item is exported as plug-in it is used in a rptlibrary. The grid with the item is added programmaticaly to one "ReportDesignHandle"-object. The text is shown as ISO 8859-1 so the german signs can't be read. I saw that the ReportDesignHandle.CHARSET is set to 8859_1 because it comes from the "IInternalReportDesignModel" iterface.
Is there any way to set the CHARSET of the "ReportDesignHandle" to UTF-8. I couldn't find any methods for that.

And how is that working in the development enviroment, but not when is exported as plug-in.

For any suggestions and hints thanks in advance.

I have modified the rotated text example 2. 
 
There ist the same problem. 
 
To modifiy it you need to change the "RotatedTextPresentationImpl"-class. Before the "BufferedImage" is created put something like: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
text = text + " ???????";
</pre>
 
After exporting this (copy it to the plugin folder) and using it into a report u can see that this text from the source file is always presented as ISO 8859-1 but the source file itself is coded in UTF-8. (Character encoding utf-8).

For now I found some workaround. 
 
I am not printing thouse chars as charset depended signs but as unicode sybols. 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
//u umalut
public static final char U_DIERESIS_SMALL = '\u00fc';
public static final char U_DIERESIS_BIG = '\u00dc';

//a umlaut
public static final char A_DIERESIS_SMALL = '\u00e4';
public static final char A_DIERESIS_BIG = '\u00c4';

//o umlaut
public static final char O_DIERESIS_SMALL = '\u00f6';
public static final char O_DIERESIS_BIG = '\u00d6';

//eszett
public static final char S_SHARP = '\u00df';
</pre>
 
 
This workaround is only good if the chars are mapping to ISO 8859-1. 
What if I want to print chinese letters. Then this solution will not fit. 
 
It should be possible to print any kind of unicode chars into the custom items.

Kosta,

Can you open a bugzilla entry for this?
