XDocReport converting odt to pdf how to set proper locale - pdf

Question

I'm trying to convert some *.odt file to *.pdf using IXDocReport.
Here is the hypothetical content of the *.odt file: ${amount?string.currency} to be paid
Here is the code I do conversion with (you can run it in kotlin REPL):
import fr.opensagres.xdocreport.converter.ConverterTypeTo
import fr.opensagres.xdocreport.converter.ConverterTypeVia
import fr.opensagres.xdocreport.converter.Options
import fr.opensagres.xdocreport.document.IXDocReport
import fr.opensagres.xdocreport.document.registry.XDocReportRegistry
import fr.opensagres.xdocreport.template.TemplateEngineKind
import java.io.ByteArrayInputStream
import java.io.File
val options: Options = Options.getTo(ConverterTypeTo.PDF).via(ConverterTypeVia.ODFDOM)
val content: ByteArray = File("/home/sandro/tmp/report.odt").readBytes()
val templateId: String = "someId"
val registry: XDocReportRegistry = XDocReportRegistry.getRegistry()
val data: MutableMap<String, Any> = mutableMapOf("amount" to 10)
ByteArrayInputStream(content).use { input ->
val report: IXDocReport =
registry.loadReport(input, templateId, TemplateEngineKind.Freemarker, true)
val tmpFile: File = createTempFile("out", ".pdf")
tmpFile.outputStream().use { output ->
report.convert(data, options, output)
println(tmpFile.toString())
}
}
and the result is the pdf file with string $10.00 to be paid
How can I set needed locale to XDocReport during conversion so the result could be changed to other currencies correctly?
P.S. I cannot control the template itself - so please do not tell me to add <#setting locale="${bean.locale}"> or something else to the template itself. The only place I can change is the code. Thanks in advance.
P.P.S. I need to render many templates per request and need to set locale per each template.

I have never used XDocReport, but maybe this will work: https://github.com/opensagres/xdocreport/wiki/FreemarkerTemplate "How to configure Freemarker?"
Quotation from there:
To configure Freemarker with XDocReport you must get the Configuration instance. To do > that you must
create a class (ex :
fr.opensagres.xdocreport.MyFreemarkerConfiguration) which implements
fr.opensagres.xdocreport.document.discovery.ITemplateEngineInitializerDiscovery.
register with SPI this class by creating the file
META-INF/services/fr.opensagres.xdocreport.document.discovery.ITemplateEngineInitializerDiscovery
with the name of you class :
fr.opensagres.xdocreport.MyFreemarkerConfiguration This file should be
in your classpath (you can for instance host it in the
src/META-INF/services/ of your project).
So you will need a class like this:
public class MyFreemarkerConfiguration implements ITemplateEngineInitializerDiscovery {
[...]
public void initialize(ITemplateEngine templateEngine) {
if (TemplateEngineKind.Freemarker.name().equals( templateEngine.getKind())) {
Configuration cfg = ((FreemarkerTemplateEngine) templateEngine).getFreemarkerConfiguration();
cfg.setLocale(...);
}
}
}
