Error - Error in base::nchar(wide_chars$test, type = "width")

Hi. I am trying to analyze mutational data with Ch37 alignment and the code is here -

MutSpot(snv.mutations = "/data/maf/mutspot_snv_copy.maf", cores = 2, cutoff.nucleotide.new = 1, genomic.features = "/data/maf/MutSpot-master/features/Ch37/genomic_features_genome_default.txt", genome.build = "Ch37")

I've tried several times but still getting this error. Is there anything I am doing wrong? Thanks for your help ahead.
