Using Canadian English(problem with US English, too), when an emdash is present
in the text with no surrounding spaces, it causes spelling errors and produces
the red wavy underline. Words separated by emdashes are separate words and
should not be treated as single entities. This has never been a problem in any
version of OO that I've ever used, until 3.2. See example text below. You can
cut-and-paste it or, alternatively, you can manually type it as in Example 2.

Example 1
Hello there
Please to—ignore all this—and this too.

Example 2
Hello there
Please to--ignore all this--and this too.
