add a chinese character inside a chart element in jasper reports

Question

When i try to display a chinese character inside a chart element(chart name) in jasper reports it doesn't display, i use i18n to take the value from properties file, it reads the keys but fails to display the chinese character. It doesn't display any character except English.

this is my jrxml:

<parameter name="chartName" isForPrompting="true" class="java.lang.String"/>
<parameter name="url" isForPrompting="true" class="java.lang.String"/>

<parameter name="wheight" isForPrompting="true" class="java.lang.String"/>
<parameter name="sql" isForPrompting="true" class="java.lang.String"/>

Answer 1

In the Properties dialog of the textfield, you should set a proper PDF-Encoding. You are using CP1252 which is ok for Latin characters but not Chinese.
