The goal: This is for an exam. I have a program which should be compiled and executed by batch script. Another batch script calls that first batch an writes the output to a .txt file. Then the contents of that .txt file should be included in a document which is produced with Latex.

The problem: Latex produces an character encoding error during the build. Error message:

Package inputenc Error: Keyboard character used is undefined in inputencoding 'utf8'

The generated file looks like this:

Ausgabe generiert am 11.05.2013 um  8:28:11,39
************** Skript zur Kompilierung der Source-Dateien **********************

Erfolgreiche Kompiliereung

In line 6 the german umlaut 'ü' (ue) is the problem. Also there is a problem with the # character later.

LaTeX config:


Code is included like this:


The strange thing, I have special characters like Umlaut (äöü) etc. all over the place in my document and that works fine. If I copy a file from my project and rename it to log.txt it works fine. But if I create a new file on the file system (or generate it with the script) and write some special characters to it, it crashes.

More details: I am using Windows 8, Texnicenter and MikTex. The listing style looks like this:


What I have tried: Googled my a.. off. I tried to use all possible codepages in the batch file like: 1250, 1252, 850, 65000, 65001, 1200, 1201, 12000, 12001. Nothing works.

I'd appreciate your help very much!

Edit Batch that writes the output:

@echo off
SET log=%~dp0\latex_doku\log\log.txt
SET skripts=%~dp0..\..\cd\batch
SET folder=%~dp0\latex_doku\log    SET result=%~dp0..\..\cd\unit_tests\results\TestResult.xml

ECHO Generieren der Ausgabedatei...
ECHO Ausgabe generiert am %DATE% um %time%>%log%

REM kompilieren
CALL %skripts%\compile.bat>>%log%

REM Systemtests ohne Eingabedateien ausfuehren
CALL %skripts%\run_tests.bat>>%log%

REM ausfuehren
CALL %skripts%\run.bat>>%log%

REM TestResults
xcopy "%result%" "%folder%" /y


When I dont specify a codepage the result looks like this:

enter image description here

When I specify cp 1252 for example it looks like this:

It is strange that the character is shown correctly in the editor...

This question came from our site for professional and enthusiast programmers.

  • Can you show the batch, that writes the output (here or at pastebin)? – Endoro May 11 '13 at 7:08
  • Yes sure, I forgot to show it. I tried different codepages with chcp command. – user1993065 May 11 '13 at 7:26
  • Does this batch write the input for Latex? Or the other called batches? – Endoro May 11 '13 at 7:31
  • It calls this one: goo.gl/gmwnk. so it creates the log.txt file which is the input for latex but the contents are produced partly by this batch, the compile batch, the program.exe and the other batches... – user1993065 May 11 '13 at 7:36
  • I have no clue. I would recommend, if you get no answer here, ask in a forum where the guys are more familiar with those special character issues (eg. chip.de or administrator.de. – Endoro May 11 '13 at 8:41

Do you know package listingsutf8?

It allows you to print a source in UTF8 (changed to Latin1) with the code:

% in preamble:

% to print the utf8 code:

Because you gave no MWE I can't test if it is working for you. Please do it by your own.
