I tried to use babel with the magyar language along with the package appendix and hyperref. There is an issue with the warnings of magyar babel and a I also had a similar problem to that one when one loads the dutch language for babel. My approach was to mix the the solutions in mweA.tex:

UseRawInputEncoding % [2]

documentclass{book}

usepackage{hyperref} % either I have it or not

usepackage[T1]{fontenc}

usepackage[utf8]{inputenc}



defmagyarOptions{defaults=hu-min} % [2]

usepackage[magyar]{babel}



usepackage[titletoc]{appendix}

usepackage{bookmark} % [1]



begin{document}



tableofcontents



begin{appendices}

chapter{test appendix}

end{appendices}

end{document}

or in mweB.tex:

documentclass{book}    

usepackage{hyperref} % either I have it or not

usepackage[T1]{fontenc}



defmagyarOptions{defaults=hu-min,suggestions=no} % [2]

usepackage[magyar]{babel}



usepackage[titletoc]{appendix}

usepackage{bookmark} % [1]



begin{document}



tableofcontents



begin{appendices}

chapter{test appendix}

end{appendices}

end{document}

(References in the code: [1] [2].) But in both cases I got the following error:

! Undefined control sequence.

GenericError  ...                                

                                                    #4  errhelp @err@     ...

l.1 ...mberline {A}test appendix}{3}{függelék.a.A}

What is going wrong here? How could I use the package appendix with magyar babel?

I figured out that without usepackage{hyperref} I got the same errors, but if I remove usepackage{bookmark}, the problems disappear. But I'd like to use the usepackage{hyperref} package.

The problematic bit seems to be

contentsline {chapter}{f"uggel'ek numberline {A}test appendix}{3}{függelék.1.A}

that is produced in the .aux and .toc file when the example is run.

In particular the fact that the last argument of contentsline, the link destination label, contains non-ASCII characters really seems to bother pdfTeX, where non-ASCII characters in label should be avoided (see Non-ASCII character in label and Non-English identifiers in label / ref ("Missing endcsname inserted")). (The MWEs both work fine with LuaLaTeX. Interestingly XeLaTeX seems to hang on something as well, which I did not expect ...)

You can instruct appendix not to use the translated string függelék as a label, but to stick with the safe appendix as defined in Hy@appendixstring instead.

With

usepackage[T1]{fontenc}

usepackage[utf8]{inputenc}

defmagyarOptions{defaults=hu-min}

usepackage[magyar]{babel}

usepackage[titletoc]{appendix}

the example should compile. The xdefHy@chapapp{Hy@appendixstring} instead of appendix.sty's defHy@chapapp{appendixname} is directly taken from hyperref.sty's definition of appendix. This is exactly what was the cause of the issue in Conflict between babel, hyperref and appendix package as well, but the workaround mentioned there did not help here - we really had to address the root of the issue directly. See also Apéndices (Appendix spanish accent), How to make appendix and hyperref packages work together with cyrillic (non ASCII) characters?, Hyperref, Bookmark and Appendix packages: Getting labels inside Appendices to work.

You should probably delete your temporary files and recompile from scratch to avoid remnants of the old code in the auxiliary files messing things up.

You may also want to consider writing to the maintainer of appendix.sty about this issue. At least to me it seems like a good idea to use the safe string Hy@appendixstring here instead of the potentially dangerous appendixname.

Note that I changed the loading order in your preamble a bit. hyperref should usually be the last package you load (there are a few documented exceptions like cleveref and some matters of taste, like the order together with bookmark: Which package should I load first: hyperref or bookmark?): It was loaded very (too?) early in your example.
