HISTORY New type in IFC Release 2x.

Per ISO 10303-11, the set of characters that may appear in STRINGs is defined in ISO 10646. The encoding of characters in case of file-based exchange is defined in ISO 10303-21 (STEP physical files) and ISO 10303-28 (XML files). Among else, these specifications define the encoding of 8-bit characters from ISO 8859-1…-16 and of 2-byte Unicode characters.

Note that while IfcText is not formally restricted in length, the size of a string in ISO 10303-21:2002 conforming exchange files must not exceed 32767 octets after encoding and escaping.
