Uploading Problems

Ok, guys, have bạn ever had this problem cuz I dunno how to fix it: Like, when bạn type your stories on Microsoft Word hoặc whatever and bạn use italics, like maybe a whole sentence in italics, it's all fine on the document, right? But when I đăng tải it, all the italic and bold letters just mash together and makes everything really hard to understand.
Have any of bạn ever had that problem? If so, do bạn know how to fix it?
