An error occurs when R tries to read csv data.How can we solve this problem?

data<-read.csv("try.csv", header=T)
make.names(col.names, unique=TRUE)

Error in : 'Sano' contains invalid multi-byte characters
appears.For character encoding,

data<-read.csv("try.csv", header=T, fileEncoding="utf-8")

If so, an error will also cause an error.How do I resolve this?
