also situations where characters have one or more spaces between them. The pair table
cannot express all aspects of line-breaking behavior, though.
A pair table, shown as Table 5-12, can also be used for quick checks.

To check whether a line break is permitted between two characters, you first look up
their
line-breaking classes and then use them as row and column ...
