[Tex/LaTex] Problems with special german characters

I am a beginner with LaTeX. I have a LaTeX template for my thesis which I have to use. The problem is that the special characters in the german language (called Umlaut) are not displayed in a correct way. Here is the code for the basic template:

Now I searched in the Internet and found many suggestions how to solve this problem. Unfortunately none of them worked in this context. Here are the suggestions which I found in the Internet and tried out:

If I use the line: "\usepackage[latin1]{inputenc} " (this is the default line of the template)
I get the message: "Latex Error: Command \textcurrenxy unavailable in encoding OT1 "

By using the line (instead of the default line) : "\usepackage[ansinew]{inputenc}"
I get the message: "Latex Error: Command \textcurrenxy unavailable in encoding OT1 "

By using the line (instead of the default line): "\usepackage[T1]{fontenc}"
I do not get an error message; nevertheless the special characters are not displayed in a correct way

By using the line (instead of the default line): "\usepackage[utf8]{inputenc}"
I get 10 errors of the type: "Package inputenc Error: Unicode char \u8:ÜR not set up for use with LaTeX" HOWEVER the special characters are displayed in a correct way and the whole document looks the way I want it to look

By using the line (instead of the default line):"\usepackage{textcomp}"
I do not get an error, but the special characters are not displayed at all (as if I have not used them)

I really tried much but without success. Can anyone help me with this problem? I would really appreciate it.

Many thanks in advance!

Update:

Thanks for your answers. Unfortunately I have still not managed to solve the problem.

I tried the solutions of Christian Lindig:

\usepackage[ngerman]{babel} % the new way
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}

and as mentioned before:
I get 10 errors of the type:

Package inputenc Error: Unicode char \u8:ÜR not set up for use with LaTeX

HOWEVER the special characters are displayed in a correct way and the whole document looks the way I want it to look. So I have 10 LaTeX errors. Do I have to live with that or is there a way not to get those errors while at the same time the document looks how it should look?

When using the second solution of Christian Linding

% \usepackage{german}       % outdated
\usepackage[ngerman]{babel} % the new way
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}

The Umlaute are not displayed in a correct way and I get one error:

Latex Error: Command \textcurrenxy unavailable in encoding T1

Best Answer

In general, I recommend working with the UTF-8 encoding for your LaTeX source code:

% \usepackage{german}       % outdated
\usepackage[ngerman]{babel} % the new way
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}

If you are working with the ISO-Latin-1 encoding, use this:

% \usepackage{german}       % outdated
\usepackage[ngerman]{babel} % the new way
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}

The T1 encoding avoids problems with umlauts and hyphenation and lmodern gives you TeX's Computer Modern fonts that fit this encoding.

[Tex/LaTex] LuaLaTeX: german special character ß with `newpxtext`

You can make the ß active and define it:

\documentclass{scrartcl}
\usepackage{newpxtext}
\catcode`\ß=13
\defß{\ss}
\begin{document}

Draußen währt am längsten.

Drau\ss en währt am längsten.

\end{document}

That's more or less what luainputenc does. But it is much better to use fontspec instead:

\documentclass{scrartcl}

\usepackage{fontspec}
\setmainfont{TeX Gyre Pagella} %palatino clone

\begin{document}
Draußen währt am längsten.
\end{document}

[Tex/LaTex] German Umlauts in US-ASCII encoding

The exported file has replaced the UTF-8 characters by macro calls \UTF{...} with the hexadecimal Unicode code point as argument. The macro could be defined in TeX, but this will not work in all circumstances (verbatim text, ...). Therefore, the best approach is to write a script/program to convert the macro calls back to the UTF-8 encoded Unicode characters.

Here a simple script sharelatex_recode.py for Python 3. It takes the file as argument and updates the file if necessary:

#!/usr/bin/env python

import argparse
import re
import sys

if sys.version_info[0:2] < (3, 2):  # tested with 3.6
    print('Python >= 3.2 is required.')
    sys.exit(1)


def main():
    args = parse_command_line()
    convert(args.input_file, args.dry_run)


def parse_command_line():
    parser = argparse.ArgumentParser(
        description=r'Replace TeX macro \UTF{...} calls to UTF-8 characters.',
    )
    parser.add_argument(
        'input_file',
        help='input TeX file',
    )
    parser.add_argument(
        '--dry-run',
        action='store_true',
        help='the file is not updated and written',
    )
    return parser.parse_args()


def convert(file_name, dry_run):
    with open(file_name, 'rb') as handle:
        data = handle.read()

    new_data, replacements = re.subn(
        br'\\UTF\{([0-9A-Fa-f]{4})\}',
        repl,
        data,
    )

    if replacements:
        print('=> Replacements: {}'.format(replacements))
        if not dry_run:
            with open(file_name, 'wb') as handle:
                handle.write(new_data)

            print('=> File written: {}'.format(file_name))
    else:
        print('=> Already uptodate: {}'.format(file_name))


def repl(match):
    code = int(match.group(1), 16)
    char = chr(code)
    utf8_sequence = char.encode('utf8')
    return utf8_sequence


if __name__ == '__main__':
    main()

The problematic line

\chapter{Vortr\UTF{00E4}ge}

becomes

\chapter{Vorträge}

It is also possible to convert all .tex files recursively, example for bash:

$ find start_directory -name \*.tex -exec python3 sharelatex_recode.py {} \;

Unicode characters outside the BMP (Basic Multilingual Plane) are not supported by the script, because I do not know, what the export of ShareLaTeX to US ASCII does in this case.
