GpgmeData value

[d_well@isuisse.com]

I have a problem when i will save a GpgmeData in a
char variable. Some special character add in the char
varialble. How can i do to have the same value in
char variable like the GpgmeData value?=20


I have do that :

while(!(err =3D gpgme_data_read ( out, buf, 100, &nread
))){
 resultText+=3Dbuf;
}

but the value of the variable resultText is not
correct.
