The desired output cannot be achieved unless your log preserves  
trailing spaces.  Thus:

00002274;Temperaturschalter mit EinstellknopfeinschlieÝÍich 2 Stk  ederspannbçÏdernzum Anlegen an Rohre bis DN 100.Max.  
Betriebsspannung: 250 VMax. Schaltleistung: 4 ASchutzart: IP  
43Schaltbereich: 30 oC bis 90 oCFabrikat: WILOTyp: Temperaturschalter TF

My suggestion is to pad with a space unless the line ends in a hyphen.

Picayune perhaps, but aesthetics (readability) counts.
