how can I make solr support Chinese dynamicField?

[zhourui]

I am using dynamicField like:
<dynamicField 
name="data_string_*"type="string"indexed="true"stored="true"docValues="true"/>
the inputDocument is:
{
"data_string_foo":"foo",
"data_string_测试字段":"bar"
}
NowI select the document,output is:
{
"data_string_foo":"foo",
"data_string_____":"bar"
}
Itseems that it does not support Chinesefield names,
how can I make solr support ChinesedynamicField?
Thanksin advance.
