Bug 20253 introduced the ability to use the basket name as a purchase order
number in the BGM segment of an EDIFACT order message. However, the basket
name was inserted into the BGM segment without escaping EDIFACT special
characters (apostrophe, colon, plus, question mark).
In EDIFACT, the apostrophe (') is the segment terminator, so any literal
apostrophe in data must be escaped with the release character (?) as ?'.
Without this, a basket name like "Children's Requests" would produce an
invalid EDIFACT message.
This fix applies encode_text() to the purchase order number in
beginning_of_message() so all special characters are properly escaped.
Test plan:
- Run t/db_dependent/Koha/Edifact/Order.t
- All tests should pass, including the new tests covering special character
escaping in BGM segments
