FRL field definition fill characters
Fill characters in FRL field definition are handled as SP-0x20
by the engine.
On the CIS GUI, when an FRL file is defined using the FRL Configurator, a value is not set for the Fill Char field. The fill characters in the .frl file are an empty value.
In the runtime, the engine sees the fill character as SP-0x20
.
This is the engine behavior. Some sub-fields do not display when the sub-field
value is only SP-0x20
and Fill Char is not set as SP-0x20
.
