H5T_SET_CSET sets the character set to be used in a dataset with a string or character datatype.
Valid values for
cset include the following:
|Character set is US ASCII|
|Character set is UTF-8, enabling UTF-8 Unicode encoding|
For example, if the character set for the datatype
dtype_id is set to
H5T_CSET_UTF8, string or character data of datatype
dtype_id will be encoded using the UTF-8 Unicode character set.
ASCII and UTF-8 Unicode are the only currently supported character encodings. Extended ASCII encodings (for example, ISO 8859) are not supported. This encoding policy is not enforced by the HDF5 library. Using encodings other than ASCII and UTF-8 can lead to compatibility and usability problems.
Note that H5T_SET_CSET sets the character set for a character or string datatype while H5P_SET_CHAR_ENCODING sets the character set used for an HDF5 link or attribute name.
