Escape new lines in FT with "\.br\" #85

Closed Denhai closed 3 years ago

Denhai commented 3 years ago

from hl7apy.core import Segment

text = "line 1\nline 2"
text = text.replace('\n', '\\.br\\')

obx = Segment('obx')
obx.obx_1 = '1'
obx.obx_2 = 'FT'
obx.obx_5 = text
print(obx.obx_5.to_er7())

# outputs:
# line 1\E\.br\E\line 2

# expected:
# line 1\.br\line 2

Am I going about this the wrong way?

Hi @Denhai. This is the correct behavior because the "\" is required to be escaped by HL7 with the sequence \E. Your counterpart should understand that that sequence should be interpreted as '\'
