How to completely disable icons?

[evgenykobz]

How can I disable showing icons whatsoever? My icons config is as follows:

           icons = {
                indent = {
                    fold_open = "",
                    fold_closed = "",
                },
                folder_closed = "",
                folder_open = "",
                kinds = {
                    Array         = "",
                    Boolean       = "",
                    Class         = "",
                    Constant      = "",
                    Constructor   = "",
                    Enum          = "",
                    EnumMember    = "",
                    Event         = "",
                    Field         = "",
                    File          = "",
                    Function      = "",
                    Interface     = "",
                    Key           = "",
                    Method        = "",
                    Module        = "",
                    Namespace     = "",
                    Null          = "",
                    Number        = "",
                    Object        = "",
                    Operator      = "",
                    Package       = "",
                    Property      = "",
                    String        = "",
                    Struct        = "",
                    TypeParameter = "",
                    Variable      = "",
                }, 
            }

And still there's an icon (that didn't load for obvious reasons):
