Standardize characters in User Guide (#17982)
Summary of the issue:
Recent updates in the User Guide have introduced non-standard characters:
right single quote (’): we usually use normal (vertical) single quote (')
em-dash (—): we usually use semi-colon or comma; we also rarely use normal dash (-). In any case, if you want to stick with a dash it should be surrounded by spaces.
Description of user facing changes
Changed these characters.
Description of development approach
Use the most common suitable characters in the User Guide.
