android - What is character 0x1f?

Question

I've just imported a chunk of text into a string element for a book app and I'm getting this error : An invalid XML character (Unicode:0x1f) was found in the element content of this document. I looked it up here http://lwp.interglacial.com/appf_01.htm and the description says US (removing underlining doesnt seem to work). What is this character so I can remove it if possible. I'm very new to android so simple answers please :)

Answer 1

0x1f is a Unit Separator, an archaic way to separate fields in a text (Like , or Tab in CSV).

It is indeed not a valid text character in XML 1.0 (but allowed in XML 1.1). In a UTF-8 input string, you can also safely replace the byte 0x1f with 0x09(Tab) to work around the problem. Alternatively, declare the document as XML 1.1 and use an XML 1.1 parser.
