UnicodeDecode Error while reading traits file

Appreciate @AdmiralenOla if you could guide me in making the approproate traits file for scoary.
scoary seems to read the gene presence absence file accurately.

Command: /home/svu/e0512807/miniconda3/envs/scoary/bin/scoary -t traits_scoary_plant_soil.tsv -g matrix_scoary_plant_soil.tsv --no_pairwise -c BH -p 1.0
Performing no pairwise comparisons. Ignoring all tree related options (user tree, population aware-correction, permutations).
Reading gene presence absence file
Ignoring relatedness among input sample and performing only population structure-naive analysis.
