v.what output is not valid JSON format

[marisn]

It seems that wxGUI vector attribute query tool is parsing text attribute values - "\" character is used as an escape character instead of its literal value. Thus \' will cause "invalid JSON" error, \b will render a backspace, \ \ (double backslash) will render as a single \ symbol.

v.db.select map=rm_me@user1                                                     
cat|title
1|\'foo,
2|ba'\'r
3|ba'
4|ba'\b'r
5|ba\\'r
