Hex values in text format file cannot be parsed. Protoc-c --encode permits hex values.

[kinyubi]

a message field is defined as uint32 in the .proto file. If the text format file specifies the value as 0xFFFF, the parse fails with the ProtobufCTextError error_txt field set to "Error found on line nn. field_xx is not an enum field."

When the value is specified as decimal 65535, no error occurs. This should be considered an error because protoc-c properly parses hex and decimal values.
