Message #04470
[Merge] lp:~m2j/openlp/work into lp:openlp
m2j has proposed merging lp:~m2j/openlp/work into lp:openlp.
Requested reviews:
Raoul Snyman (raoul-snyman)
Jon Tibble (meths)
- openlp.org 1.x importer detects the character encoding for the database and shows a inputDialog for correcting the guess.
- prefer UTF-8 encoding for CCLI import
- split song order at consecutive white spaces (it rejected song orders with two consecutive spaces)
