I am trying to support UTF-8 characters in my ANT script.

As long as the character string are made up of 2-byte UTF-8 characters, such as:

  • Lògìñ
  • Ùsèr ÌÐ

Then things work fine.

When I use Unicode Han Character:

  • ?

Which, according to this site: http://www.fileformat.info/info/unicode/char/6211/index.htm Has a UTF-8 encoding of 0xE6 0x88 0x91

I can see in UltraEdit, my input properties file has the values "E6 88 91" all in a row, so I'm fairly confident that my input is correct. And When I open the same file in Notepad++ I can see all the characters correctly.

Here is my Build Script:

    <?xml version="1.0" encoding="UTF-8" ?>

    <project
        name="utf8test"
        default="all"
        basedir=".">

        <target name="all">
            <loadproperties  encoding="UTF-8" srcfile="./apps.properties.all.txt"  />

            <echo>No encoding ${common.app.name}</echo>
            <echo encoding="UTF-8">UTF-8 ${common.app.name}</echo>
            <echo encoding="UnicodeLittle">UnicodeLittle ${common.app.name}</echo>
            <echo encoding="UnicodeLittleUnmarked">UnicodeLittleUnmarked ${common.app.name}</echo>
            <echo>${common.app.ServerName}</echo>
            <echo>${bb.vendor}</echo>

            <echo>No encoding ${common.app.UserIdText}</echo>
            <echo encoding="UTF-8">UTF-8 ${common.app.UserIdText}</echo>
            <echo encoding="UnicodeLittle">UnicodeLittle ${common.app.UserIdText}</echo>
            <echo encoding="UnicodeLittleUnmarked">UnicodeLittleUnmarked ${common.app.UserIdText}</echo>

            <echoproperties />
      </target>
    </project>

And here is my properties file:

    common.app=VrvPsLTst
    common.app.name=??
    common.app.description=Pseudo Loc Test App for Build Script testing
    common.app.ServerName=http://Vèrìvò.com

    ios.RegistrationURL=http://www.josscrowcroft.com/2011/code/utf-8-multibyte-characters-in-url-parameters-%E2%9C%93/

Here is what the output looks like:

Thank you for your help

EDIT\UPDATE 6/19/2012

I am developing in a Windows environment.

I have installed a TTF from: http://freedesktop.org/wiki/Software/CJKUnifonts/Download

I have updated UltraEdit to use the TTF and I can see the Chinese characters.

    <?xml version="1.0" encoding="UTF-8" ?>

    <project name="utf8test" default="all" basedir="."> 

    <target name="all"> 


      <echo>??</echo>
      <echo encoding="ISO-8859-1">ISO-8859-1 ??</echo> 
      <echo encoding="UTF-8">UTF-8 ??</echo> 


      <echo file="echo_output.txt" append="true" >?? ${line.separator}</echo>
      <echo file="echo_output.txt" append="true"  encoding="ISO-8859-1">ISO-8859-1 ?? ${line.separator}</echo> 
      <echo file="echo_output.txt" append="true"  encoding="UTF-8">UTF-8 ?? ${line.separator}</echo> 
      <echo file="echo_output.txt" append="true"  encoding="UnicodeLittle">UnicodeLittle ?? ${line.separator}</echo> 
      <echo file="echo_output.txt" append="true"  encoding="UnicodeLittleUnmarked">UnicodeLittleUnmarked ?? ${line.separator}</echo> 

    </target> 
    </project> 

The output captured by running inside UltraEdit is: Buildfile: E:\temp\utf8\build.xml

    all:
         [echo] ??
         [echo] ISO-8859-1 ??
         [echo] UTF-8 ??

    BUILD SUCCESSFUL
    Total time: 1 second

And the echo_output.txt file shows up like this:

    ?? 
    ISO-8859-1 ?? 
    UTF-8 ?? 
    ÿþU n i c o d e L i t t l e   ? ?   

     U n i c o d e L i t t l e U n m a r k e d   ? ?   

So there appears to be somehting fundamentally wrong with how my ANT environment is set up since I cannot simply echo the character to the screen or to a file.
