Cryptanalysis

Hi,

As it is Monoalphabetic substitution cypher, I tried listing all possible outputs using a python script. As described in the challenge itself, I tried trimming the last and first character of 26 possibilities. none of them worked. I guess it may be in another language, so I tried to translate it to English from french using google translator. But, it didn’t works out. Any help on this ?

There is more than 26 possibilities
