Croatian digraph capitalization

[vedranmiletic]

When the template requires the chapter to be printed in all caps in Croatian (e.g. Sphinx template does it), with current digraph configuration it will be printed out as

POGLAVljE,

while it should be

POGLAVLJE.

Note the capital LJ instead of lj. Is there any way to enable digraph to be capitalized?

CC'ing @ivankokan who I know has been working on this previously.

Hi @vedranmiletic, can you please provide some MWE?

@ivankokan does the following help?

This is not really minimal, and I cannot compile it (due to sphinx class not available here). However, can you try if the following helps?

\makeatletter
\addto\captionscroatian{
  \def\chaptername{Poglav\protect\xpg@hr@digraph{l}{j}e}%
}
\makeatother

At least this solves the following MWE (which does not compile without the fix):

\documentclass{report}
\usepackage{fontspec}
\usepackage{polyglossia}
\setmainlanguage{croatian}

\setmainfont{FreeSerif}

\begin{document}

    \MakeUppercase{\chaptername}

\end{document}

Let's assume this is fixed. Please report if not.
