Hello,
I read / write strings in my HDF files to copy data between Matlab and my C++
code. I have some problems with ASCII Codes greater 127 in my files.
The dump of a HDF5 file (Matlab) shows:
GROUP "/" {
DATASET "data" {
DATATYPE H5T_STRING {
STRSIZE 2;
STRPAD H5T_STR_NULLTERM;
CSET H5T_CSET_ASCII;
CTYPE H5T_C_S1;
}
DATASPACE SIMPLE { ( 4 ) / ( 4 ) }
DATA {
(0): "\37777777744", "\37777777766", "\37777777774", "\37777777737"
}
}
}
The chars are "ä", "ö", "ü", "ß". My code creates the same chars of a string
with string.c_str() to:
GROUP "/" {
DATASET "test" {
DATATYPE H5T_STRING {
STRSIZE 3;
STRPAD H5T_STR_NULLTERM;
CSET H5T_CSET_ASCII;
CTYPE H5T_C_S1;
}
DATASPACE SIMPLE { ( 4 ) / ( 4 ) }
DATA {
(0): "\37777777703\37777777644", "\37777777703\37777777666",
(2): "\37777777703\37777777674", "\37777777703\37777777637"
}
}
}
It seems that my code create 2 bytes for the ä, ö, ü, ß and Matlab 1 byte. Can
I switch the encoding in the HDF5 file or can I use unicode or anything else?
Thanks
Phil
