#*
#* Unit test for the COD::CIF::Data::CODFlags::has_Fobs subroutine.
#* Tests the way the subroutine behaves when the input data block contains
#* various data items that should normally state that the entry has a related
#* diffraction file. However, in this particular case these items contain
#* special values such as ('.' and '?') that are treated the same way as if
#* the data item was not present at all.
#*
#* NOTE: currently the subroutine does not differentiate between special
#* CIF values (unquoted '?', '.') and regular question mark and dot symbols
#* (quoted '?', '.'). This behaviour should be investigated further.
