Problems with the capitalization of German umlauts

[Magger]

The following minimum working examples describes the problem:

\documentclass{scrartcl}

\usepackage[utf8]{inputenc}

\usepackage[
style=ieee,
backend=biber,
]{biblatex}

\addbibresource{test.bib}

\usepackage{filecontents}
\begin{filecontents}{test.bib}
@INPROCEEDINGS{test,
author = {Mustermann, Max},
title = {{E}in {T}itel mit {Ö}ffnungen},
year = {2014},
month = apr
}
\end{filecontents}

\begin{document}

\nocite{*}
\printbibliography

\end{document}

The problem is that the letter 'Ö' is not being written as a capital letter in the pdf output file, although it is put into curly braces. I'm using biber 1.8 under MikTeX 2.9.

Can you try the biber 1.9 dev version from Sourceforge (you'll need to be using the biblatex 2.9 dev version from SF too). I don't see your problem with that version.

How can I (easily) install this on MikTeX 2.9 without much interference with
my normal installation of Biber 1.8?

Biber is just a stand-alone binary which you can drop over your existing biber (or just rename the new one to “biber1.9.exe” and use that name to run it. biblatex is a bit tricker - you should install it in a local texmf tree if you don't want to overwrite your existing biblatex. The best thing to do is to ask on TSE - this is a common question about using development versions.

I tested with biber 1.9 (and also with 2.0): It still eats a level of braces to much. That means the example of Magger leads to this in the bbl:

    \field{labeltitle}{{E}in {T}itel mit Öffnungen}

As you can see the braces around {E} and {T} are still there, while the Ö lost its braces. (It has nothing to do with the ieee-style. But there the missing braces are important. Using two braces {{Ö}} leads to {Ö} in the bbl.

Hmm, strange, with this .bib and 1.9 DEV:

@Article{test,
  AUTHOR                    = {Alan Smith},
  TITLE = {{E}in {T}itel mit {Ö}ffnungen},
  YEAR                      = {2010},
}

The .bbl looks fine for me

\field{labeltitle}{{E}in {T}itel mit {Ö}ffnungen}

With your bib there is no problem. But I could reproduce it with this bib:

@book{eichenbaum,
author={{\.{E}}jchenbaum},
}

@INPROCEEDINGS{test,
  author = {Mustermann, Eva},
  title = {{E}in {T}itel mit {Ö}ffnungen},
  year = {2014},
  month = apr
}

It looks as if the accent in the first bib entry (which is actually not used in the test document) somehow change the second entry.

I get
\field{labeltitle}{{E}in {T}itel mit Öffnungen}
with the bib above and
\field{labeltitle}{{E}in {T}itel mit {Ö}ffnungen}
if I change the author to Ejchenbaum.

@u-fischer - Please try the 1.9/2.0 versions just uploaded to SF - this should be fixed.

I tried out 1.9. and it seems to be fixed. Same for the other problem with the keywords. My bib now process fines and shows the missing fields.
