escape string containing backslash

[flamingofugang]

Hi,

When I convert a hdt file using hdt-cpp tool hdt2rdf, the generated nt file cannot be read by hdt-mr.

I got the following error:

Error: java.lang.IllegalArgumentException: Unescaped backslash in: "buttpark 63\09-92"@en

shall we make less strict rule in the class org.rdfhdt.hdt.util.UnicodeEscape?

Best,

What does the original string here look like? Does it have a backslash character, or is it trying to escape the \09 character code?
