Java – character encoding of Jasper Report PDF format
•
Java
I want to use custom fonts in Jasper reports Myanmar 3 is the standard font in Myanmar
When exporting a report to an HTML file It can display the report title However, the exported PDF file does not display correctly
In the browser
In PDF
public void report() throws Exception {
List<SalesReport> saleReports = salesReportService.findSalesReport(new SalesReportCriteria());
InputStream inputStream = new FileInputStream("report-template/saleReportTemplate.jrxml");
String outputFilePdf = "D:/temp/BasicReport.pdf";
String outputFileHtml = "D:/temp/BasicReport.html";
Map paramMap = new HashMap();
paramMap.put("ReportTitle","\u1005\u101B\u1004\u103A\u1038\u1021\u1004\u103A\u1038\u1019\u103B\u102C\u1038\u1011\u100A\u103A\u101E\u103D\u1004\u103A\u1038\u1001\u103C\u1004\u103A\u1038");
paramMap.put("TableDataSource",new JRBeanCollectionDataSource(saleReports));
JasperDesign jasperDesign = JRXmlLoader.load(inputStream);
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,paramMap,new JRBeanCollectionDataSource(saleReports));
JasperExportManager.exportReportToPdfFile(jasperPrint,outputFilePdf);
JasperExportManager.exportReportToHtmlFile(jasperPrint,outputFileHtml);
}

I have added myanmar3 Ttf file and in jasperreports-fonts-5.1 0. Jar for myanmar3 font configuration
jasperreports_ extension. properties
net.sf.jasperreports.extension.registry.factory.simple.font.families=net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory net.sf.jasperreports.extension.simple.font.families.dejavu=net/sf/jasperreports/fonts/fonts.xml net.sf.jasperreports.extension.simple.font.families.myanmar3=net/sf/jasperreports/fonts/fonts.xml
font. xml
...other default config.
<fontFamily name="Myanmar3">
<normal>net/sf/jasperreports/fonts/myanmar3/MYANMAR3.TTF</normal>
<bold>net/sf/jasperreports/fonts/myanmar3/MYANMAR3.TTF</bold>
<italic>net/sf/jasperreports/fonts/myanmar3/MYANMAR3.TTF</italic>
<boldItalic>net/sf/jasperreports/fonts/myanmar3/MYANMAR3.TTF</boldItalic>
<pdfEncoding>Identity-H</pdfEncoding>
<pdfEmbedded>true</pdfEmbedded>
</fontFamily>
I have tested many configurations, references and examples However, it has no effect on PDF files
If you have any suggestions and provide, please let me know
Solution
This is a problem with iText (version test 5.5.4) and TTF fonts. IText does not support ligatures. Please refer to the comments below
Because Jasper reports uses iText as its library to render PDF, this problem cannot be solved in Jasper reports
The sample code using iText only will render the same output as the Jasper report
public class FontTest {
/** The resulting PDF file. */
public static final String RESULT = "pdf/fontTest.pdf";
/** Test text. */
public static final String TEST = "\u1005\u101B\u1004\u103A\u1038\u1021\u1004\u103A\u1038\u1019\u103B\u102C\u1038\u1011\u100A\u103A\u101E\u103D\u1004\u103A\u1038\u1001\u103C\u1004\u103A\u1038";
public void createPdf(String filename) throws IOException,DocumentException {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document,new FileOutputStream(filename));
document.open();
BaseFont bf = BaseFont.createFont(
"lib/myanmar3.ttf",BaseFont.IDENTITY_H,BaseFont.EMBEDDED);
Font font = new Font(bf,20);
ColumnText column = new ColumnText(writer.getDirectContent());
column.setSimpleColumn(36,730,569,36);
column.addElement(new Paragraph(TEST,font));
column.go();
document.close();
}
public static void main(String[] args) throws IOException,DocumentException {
new Fonttest().createPdf(RESULT);
}
}
I posted a follow-up question in the iText section to understand why iText does not render fonts correctly
