Description alex.stewart 2006-04-20 14:25:33 CEST 
I maintain a vrml/x3d browser for Linux/Unix. A user submitted a vrml file
generated by geant. It contains many lines like:

#---------- SOLID: av_1_impr_1_/t2k/OA/Magnet/LeftClam/CoilTopFrontBend_pv_0^@.1

where the "^@" is actually a null character. (0x00 in hexadecimal)

Null characters are used in Unix (OSX, Linux) to signify end of string.

I suggest changing the code to remove this null character. It affects the
way FreeWRL operates, and it may also affect the way other programs
interpret the output of Geant4.
