devanagari i18n in java

我正在尝试使用i18n在java中使用来自互联网的示例ttf文件来使用devanagari / hindi。

我能够加载资源包条目并加载ttf和设置字体,但它不会根据需要呈现jlabel。它显示了代替字符的块。如果我在eclipse中调试,我可以将鼠标悬停在unicode变量上,甚至可以渲染devanagari。下面是代码和资源包供参考。

package i18n;

import java.awt.Font;
import java.awt.GridLayout;
import java.io.InputStream;
import java.util.Locale;
import java.util.ResourceBundle;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class MyNumbers extends JFrame {
    private ResourceBundle rb;
    private Font devanagariFont;

    public MyNumbers (String language, String fontFile) {
        loadResourceBundle(language);
        loadFont(fontFile);
        display();
    }

    private void display() {
        String unicode = null;

        JPanel labels = new JPanel(new GridLayout(0,2));
        JLabel uni = null;
        for(int i=0; i<=10; i++) {
            unicode = rb.getString("" +i);
            labels.add(new JLabel("" + i));
            labels.add(uni = new JLabel(unicode));
            uni.setFont(devanagariFont);
        }
        getContentPane().add(labels);
        setDefaultCloseOperation(DISPOSE_ON_CLOSE);
        pack();
        setVisible(true);
    }

    private void loadFont(String fontFile) {
        try {
            InputStream input = getClass().getResourceAsStream(fontFile);
            Font b = Font.createFont(Font.TRUETYPE_FONT, input);
            devanagariFont = b.deriveFont(Font.PLAIN, 11);

        } catch(Exception e) {
            e.printStackTrace();
        }
    }

    private void loadResourceBundle(String language) {
        String base = getClass().getName() + "rb";
        rb = ResourceBundle.getBundle(base, new Locale(language));

    }

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        new MyNumbers("hi", "Devnew.ttf");
    }

}

这是我创建的MyNumbersrb_hi.properties的资源包。

尝试使用此https://stackoverflow.com/a/6995374/466250 正如原始问题所说,默认情况下属性文件是ISO-8859-1。

答案 1 :(得分:0)

只是不要在unicode的标签上设置字体,默认字体能够正常渲染。

答案 2 :(得分:0)

尝试运行SymbolText小程序,选择900范围,然后选择您要使用的字体。将结果与选择标准字体(如Devanagari MT)进行比较。您的字体版本与JVM上的TrueType实现之间可能存在不兼容。

尝试调用getFontName(),getNumGlyphs(),canDisplay()和canDisplayUpTo()来验证您加载的字体是否符合预期。

既然您知道Eclipse可以呈现Devanagari,请尝试识别并使用Eclipse使用的字体(如果需要)。

使用utf-8加载资源

ResourceBundle messages = ResourceBundle.getBundle(“resources / MenuBarResources”,locale,new UTF8Control());

public class UTF8Control extends Control {
public ResourceBundle newBundle
    (String baseName, Locale locale, String format, ClassLoader loader, boolean reload)
        throws IllegalAccessException, InstantiationException, IOException
{
    // The below is a copy of the default implementation.
    String bundleName = toBundleName(baseName, locale);
    String resourceName = toResourceName(bundleName, "properties");
    ResourceBundle bundle = null;
    InputStream stream = null;
    if (reload) {
        URL url = loader.getResource(resourceName);
        if (url != null) {
            URLConnection connection = url.openConnection();
            if (connection != null) {
                connection.setUseCaches(false);
                stream = connection.getInputStream();
            }
        }
    } else {
        stream = loader.getResourceAsStream(resourceName);
    }
    if (stream != null) {
        try {
            // Only this line is changed to make it to read properties files as UTF-8.
            bundle = new PropertyResourceBundle(new InputStreamReader(stream, "UTF-8"));
        } finally {
            stream.close();
        }
    }
    return bundle;
}
}
