#3133: v.what output is not valid JSON format
-------------------------+-------------------------
 Reporter:  marisn       |      Owner:  grass-dev@…
     Type:  defect       |     Status:  new
 Priority:  normal       |  Milestone:  7.3.0
Component:  wxGUI        |    Version:  svn-trunk
 Keywords:  v.what       |        CPU:  Unspecified
 Platform:  Unspecified  |
-------------------------+-------------------------
 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 at user1
 cat|title
 1|\'foo,
 2|ba'\'r
 3|ba'
 4|ba'\b'r
 5|ba\\'r
 }}}
