If you want to change the appearance of your document, say, from serif to sans-serif fonts, you can change the whole document in one go and the Greek will match the look-and-feel of the rest of the text (fonts permitting).If you share your documents (with colleagues, students, a publisher, on the web, etc.) your correspondents will not need a specific font to view your text, as Unicode is a universal standard.
Rather, you should type all Latin, Greek, Hebrew, Russian, Chinese, etc.
Regardless of whether you use Windows, Linux, or Mac, the first answer to this question is that you should not be using a font that replaces Latin letters with the shapes of Greek letters (which typifies fonts created in the 1980s and 1990s). What Greek fonts should I use on my computer?
