(I am not quite sure if this qualify as a valid Question)
Italic words are often used in midst of running upright text, either for emphasis or other purpose, such as for foreign languages. According to Robert Bringhurst, the italic punctuations shall be used following italic text, since they give better fit. (page 60 or The Element). This is quite sensible, however, there is one situation that I am not sure about,
Say the italic text is preceded (or followed) by a left (or right) quotation mark, either single or double, shall it be also in italic? I think there a few practice, all have some merits of sense
- They shall be from the upright font, i.e., treat them like delimiters, if surrounding (outside the quotations) are upright.
- Always use italic quotation marks, since they give better fit (however, in LaTeX this may be less of an advantage given the automatic handling of italic corrections by
\emphetc). This means that it is possible that an upright left quotation mark is paired with an italic right mark, and vice versa
- If the whole quotation is in italic, from the left quotation mark to the right one, then both quotation marks are in italic, otherwise (that is, either the left quotation marks is followed by upright text or the right quotation mark is preceded by upright text), then both are in upright font.
At the moment I use the third one. However, it seems to me to lack some consistency. Are there any standard style guide that touch this issue? (preferably with some explanation or discussions on the reasoning.)
