Formatted Text Data (FT) -- HL7v2 primitive data type.
Lossless storage: the value is stored and returned as a plain binary string.
The HL7 spec says FT supports embedded formatting commands (e.g., \.sp\
for vertical spacing), but this implementation preserves all input bytes
for round-trip fidelity. No formatting interpretation, escape processing,
or length enforcement is performed.
