I get the error below with an Ant skript I wrote.

I already did some googling and found out, that the problem lies with strings containing \u, which happens under Windows because of the directory separator. I changed all those to / but the error remains.

There are definitely no remaining \u strings in my script.

java.lang.IllegalArgumentException: Malformed \uxxxx encoding.

The error occurs when executing the propertyfile task, so I examined the file I want to change. This on the other hand contains multiple \u strings. The file has no relation to ant though, it's a borland project file (xml) which contains one line like [someParameter]=[someValue].

I just want to increase [someValue] by 1.

So my question is:

Can the property file I want to change cause the error mentioned

and if the answer is "yes",

What can I do, other than doing it with a regex task (like finding the line, propertyregex-ing the value, math+1 the value and regex-replacing the value)
