It depends more on the font you use. The X fonts made the backtick more vertical than it should be. The apostrophe (single quote) was also slightly angled. This led to the backtick and apostrophe being used as way of faking smart quotes.

With newer fonts, the backtick is more angled and easier to distinguish. Try switching the font on your editor or terminal window to something else. Any of the scalable (TrueType) fonts would do it.

Title:
Use:  <p> text here (a paragraph) </p>

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
