How it works
Standard: HL7 v2 escape sequences (field, component, subcomponent, repetition and escape characters)
Formula: \F\ = | \S\ = ^ \T\ = & \R\ = ~ \E\ = \ \.br\ = line break \Xhh..\ = hex bytes
Checks: Unbalanced or unknown escape sequences reported with position; hex sequences must be valid UTF-8
