Using echo is a good way of checking just what the shell is handing to 
your program.  But I totally agree that this is a major interoperability 
annoyance.

I'm using Bash 4.4.12(3):

$ echo \\192.168.1.5\wwwroot\ccenter\bin\online.sh
\192.168.1.5wwwrootccenterbinonline.sh

$ echo "\\192.168.1.5\wwwroot\ccenter\bin\online.sh"
\192.168.1.5\wwwroot\ccenter\bin\online.sh

$ echo '\\192.168.1.5\wwwroot\ccenter\bin\online.sh'
\\192.168.1.5\wwwroot\ccenter\bin\online.sh

$ echo \\foo\wwwroot\ccenter\bin\online.sh
\foowwwrootccenterbinonline.sh

$ echo "\\foo\wwwroot\ccenter\bin\online.sh"
\foo\wwwroot\ccenter\bin\online.sh

$ echo '\\foo\wwwroot\ccenter\bin\online.sh'
\\foo\wwwroot\ccenter\bin\online.sh


read -r is an alternate way of getting text into a command line that 
might otherwise turn into quoting hell.

$ read -r; cygpath -u $REPLY
\\192.168.1.5\wwwroot\ccenter\bin\online.sh
//192.168.1.5/wwwroot/ccenter/bin/online.sh
