I'm guessing that this is a hack to encode actual parenthesis rather than (/) rough/smooth breathing marks, which should rather have been encoded in Beta Code as [1/]1.

Perseus 5.0 turns them into literal parentheses, U+0028 and U+0029.

@sasansom, any opinion? Is converting these to normal parenthesis (i.e., Beta Code [1 and ]1) the right thing?

NB There was also a pair at Theoc. 8.51, as reflected in known.py, but all of Theoc. 8 was deleted in 42da31d.
