Why is the bitwise «or» (vertical line) removed

Hello!
В options -- Add Option -- after the sign: ~ real
Why is the bitwise «or» ( | vertical line) removed?
There is a way how you can insert a bitwise «or» into the real value?

The pipe character is used internally to separate the display and real value. It cannot be used in the data.
