Mosaic didn't really handle charsets. It used Motif as the underlying toolkit, and rendered the binary text stream using XmSTRING_DEFAULT_CHARSET, which could default to ISO 8859-1 most of the time, or something else if you tweaked your X11 installation and properties. So, basically, Mosaic worked as firefox/opera do, not as IE. -- Vincent ARCHER varcher () denyall com Tel : +33 (0)1 40 07 47 14 Fax : +33 (0)1 40 07 47 27 Deny All - 23, rue Notre Dame des Victoires - 75002 Paris - France
