Hi Jurko,

Thanks a lot for the test-case - I should have provided one myself ...

It has echo off:

@echo off

setlocal enableextensions enabledelayedexpansion
set THISDIR=%~dp0

echo start loop

for %%I in ( %THISDIR%src\*.txt ) do (
    rem %%~nxI is equivalent to `basename "${I}"` . see "FOR /?"
    echo converting %%I
    echo to %%~nxI
    iconv -f iso-8859-1 -t utf-8 %%I > %%~nxI

echo end loop

And the python bit I changed to

# import os
# os.system( "worker.bat" )

import subprocess
command = ["worker.bat"]

Same here, I changed to following to mimick my situation better
- use of subprocess (so Python can mess up stdin/out)
- a small loop in the .bat file

I tried - I cannot reproduce my claim (yet)

I will try harder; as I had the situation in our build: with bjam 3.1.14
all went smoothly, with bjam 3.1.16 the builds went down because somehow
output was redirected to the wrong file ..

It might be in the python bit, as popen does its own magic with

It does!
