Answer 1

In my case, I'm using Maven 3.3.3 to build my releases. The maven-resource-plugin was filtering the resources and applying UTF-8 in font files (.ttf).

So, I added this configuration and it solved the problem.

<build>
    <resources>
        <resource>
            <directory>${project.basedir}/src/main/resources</directory>
            <filtering>false</filtering>
            <includes>
                <include>**/jasperreports_extension.properties</include>
                <include>**/tecsofti-fonts.xml</include>
                <include>**/*.ttf</include>
            </includes>
        </resource>
    </resources>
</build>

Answer 2

I managed to solve it by changing relative URL of font to absolute URL. But i don't know why relative URL causes that problem.

Answer 3

我将/fonts/FONT.TTF替换为./fonts/FONT.TTF并且工作正常注意：替换fonts.xml和resources \\ jasperreports_extension.properties
