After using the Pi symbol (\Pi), my text changes to a different font and goes to italic. How can I resolve this?

    Neither \Pi nor \pi should even work in text mode, unless the command has been redefined and producing something ( completely different?)

  • Probably you forgot a closing $. Could you post a minimal example?

  • If you want to write the mathematical symbol, try putting dollar signs around \pi. If you want to write text in the Greek language, not mathematics, consider tex.stackexchange.com/questions/100690/… Apr 19, 2016 at 7:33

Use $\Pi$. In this case, math expressions have to be between dollar signs.

    @Romain Picot - Imho this provides an answer to the question.

    It might be. However, since the OP does'nt provide any MWE, it could be due to a missing $ or a redefinition of \pi as pointed by ChristianHupfer. My comment is more, that we should wait for clarification from the OP before to guess as solution Apr 18, 2016 at 14:57
  • OK, I understand.

  • @RomainPicot: Perhaps some black magic with \ensuremath ... ;-)
