remove iconv lib dependency from Libxml2

[ayeshagutpa]

hi all

I need to remove lib iconv dependency from libxml2.
I have found that while configuring the libxml2 there is an option like ICONV=NO .but my question is

what does cscript configure.js iconv=no imply when configuring libxml2 for windows environment?

does it mean , that libxml2 has internal implementation of iconv or does it completely
ignore libconv by enabling some flag?
how to confirm if the dependency is completely removed from libxml2.

Thanks

Regards
