Using the italics class breaks the encoding of my page and results in garbled text when trying to print.
using:
chrome: Version 78.0.3904.108 (Official Build) (64-bit)
mac-os: Version 10.15.1 (19B88)
Using Chrome's print preview I get the following preview with garbled text instead of the expected text of Making this text italic breaks the encoding for this document in print (which you can see in the background).

When I remove either the italic class or the tailwind import the issue goes away. Applying the css font-style: italic manually without any tailwind works normally and doesn't cause any issue.
I've created a minimal reproduction of the issue here https://codesandbox.io/s/static-cmn0x. The issues is reproducible by following these steps:
I really can't think of any reason why things would get messed up when using .italic besides something being wrong with the fonts you're using. Since you're not even using custom fonts, I'm not sure where this could be coming from but I can say it looks good on Safari and Firefox (not Chrome Canary though).
Have you checked how this looks like on other Chromium-based browsers?
Dug into it a bit more and seems to be an issue with the BlinkMacSystemFont font. I've created an example without tailwind but with a list of <p> each using one of the font-families defined in the tailwind fontstack. (https://codesandbox.io/s/static-uwipl)

As you can see, only the row with BlinkMacSystemFont is showing the issue.

Found out about this bug the hard way.
Came here to report it & saw this issue. It's still unresolved as of now in chromium.
If it may help others: Just remove italics and your print/preview will render fine.
