Windows character set codes are different from thos in DOS or Unicode. (The £ symbol is code 156 in DOS but 163 in Windows.)  In Windows 95 or later you can get non-Western fonts enabled via Microsoft Plus. If your texts were written using a Windows word-processor and saved as text in Windows, the accented characters will obey the Windows codes. You will have access to a few more symbols than in DOS (e.g. ®,©,™ and curly apostrophes).
