Don't know if you can get MatLab to use UTF-8, concerning the
HDF5 file the question is how it is written. The program it's
written by seems to use UTF-8. Can you change that? If this
is a test program with the 'äöüß' hard-coded into it you just
may have to get your editor to use ISO-8859-1. Writing to the
HDF5 file isn't the point, it just contains what you told it
to, the problem is passing in the values you want it to con-
tain.
I've tested the code with ISO-8859-1 (change my source code,
because the chars are hardcoded), than the encoding is correct (C++
& Matlab). But my problem I read XML data with utf-8 encoding (some
cyrillic chars, etc). I would like to write them to the HDF and
read them into Matlab. Do you have any idea with a correct encoding?
If I read / write the char data in my code, I can set the correct
encoding representation, but is there an option for saving the
encoding into the file, because only the char code isn't unique. I
can set utf-8, utf-8, ASCII, etc
Would the H5Tset_cset() routine (http://www.hdfgroup.org/HDF5/doc/RM/RM_H5T.html#Datatype-SetCset
) help out here?
Thanks, but if I use this call:
H5::StrType l_str(0, p_strlen+1);
l_str.setCset( H5T_CSET_UTF8 );
the dump of a file shows:
DATATYPE H5T_STRING {
STRSIZE 29;
STRPAD H5T_STR_NULLTERM;
CSET H5T_CSET_ASCII;
CTYPE H5T_C_S1;
}
No exception is thrown or something else. It seems, that the string
object does not set the H5T_CSET_UTF8
