Line break rules for word wrapping in PDFs have changed
slightly from the last release. Brackets and parenthesis such as {
} and ( ) are now treated as breakable. For example, in past releases,
the following string would be treated as a single non-breaking string.
Boilers(Steam)
In this release, "Boilers" and "(Steam)" are treated as separate
strings which might result in the following when the string occurs
at the end of a line.
Boilers
