Description:
HTML Wrap
classhdf-rm-section

H5Tset_cset sets the character set to be used in a dataset with a string or character datatype.

Valid values for cset include the following:

        H5T_CSET_ASCII    Character set is US ASCII.
 H5T_CSET_UTF8 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 H5Tset_cset sets the character set for a character or string datatype while H5Pset_char_encoding sets the character set used for an HDF5 link or attribute name.
