Data encoding in hdf5.jl

Hi all,

I have a tiny question involving hdf5.jl package. To be more specific, consider the following info related to a given .h5 file:

 DATASET "j" {
      
    DATATYPE  H5T_STD_I64LE
      DATASPACE  SIMPLE { ( 10 ) / ( 10 ) }
        DATA {
        (0): 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
        }
           ATTRIBUTE "CLASS" {
               DATATYPE  H5T_STRING {
                   STRSIZE 15;
                   STRPAD H5T_STR_NULLTERM;
                   CSET H5T_CSET_UTF8;
                   CTYPE H5T_C_S1;
                }
             ....
            }
 }

My question is: Is there any command within the hdf5.jl package that allows me to change from " CSET H5T_CSET_UTF8" to " CSET H5T_CSET_ASCII" in the ATTRIBUTE “CLASS” block?

Thanks in advance!
