Special char-set usage

[giveen]

Am I doing this right?

Code:

oclHashcat-plus64.exe -a 3 -m 100 -p : --session=05100218 --force -o "F:\hashcat\output\argentina_sha1_found.txt" --outfile-format=2 -n 40 --markov-disable --remove -u 250 --gpu-temp-disable -1 F:\hashcat\oclHashcat-plus-0.15\charsets\special\Spanish\es_ISO-8859-1-special.hcchr "F:\hashcat\hashes\hash.org\argentina_sha1.txt"

I know the file is an argentine hash file, so I am assuming Spanish, but I don't appear to be finding anything.
