I am using XeLaTeX with the memoir class and Greek text and I would like to change the chapter title to be uppercase instead of lowercase

I have this

\chapter{Αποτελεσματικότητα του Ανταγωνιστικού Υποδείγματος}

and I get this

Κεφάλαιο 1 Αποτελεσματικότητα...

Instead, I would like to get this

ΚΕΦΑΛΑΙΟ 1 Αποτελεσματικότητα

    Welcome to TeX.SX! Please provide a minimal working example (MWE) showing the format you are using. Do want to change the chapter number of the chapter name? Commented Nov 10, 2014 at 15:07
  • Memoir class defines \chaptername as {Chapter} and \chapterrefname as {Chapter-} You can redefine them using \renewcommand* or \def. Commented Nov 10, 2014 at 15:32
  • @JohnKormylo I tried \renewcommand{\chaptername}{ΚΕΦΑΛΑΙΟ} but didn't see any changes

  • @SofiaMouseti Is the accent suppressed when all uppercase is used?

Following the suggestion in How to change the name of document elements like "Figure", "Contents", "Bibliography", "Appendix", etc.?, you need to add the new \chaptername to the greek captions using


Here is a minimal example showing the adjustment:

Alternatively, without the above approach, a delayed \renewcommand also suffices:

  \renewcommand*{\chaptername}{\textKappa \textEpsilon \textPhi \textAlpha \textLambda \textAlpha \textIota \textOmicron}}
  • First solutuion did not work (i use polyglossia package because of zelatex, not babel, if that's the reason), The alternative worked fine, thank u

    @SofiaMouseti, such details are quite important to include in the original question. Along with a minimal example.
