Description

Encoding is an enumeration type describing different kinds of string encodings which will be supported by OTX applications.

The list of allowed enumeration values is defined as follows:

Value	Literal	Description
US-ASCII	@Encoding:US-ASCII	String encoding specified by [ISO/IEC 646]
ISO-8859-1	@Encoding:ISO-8859-1	String encoding specified by [ISO/IEC 8859-1]
UTF-8	@Encoding:UTF-8	String encoding from the UTF encoding family, see [ISO/IEC 10646]
UTF-16BE	@Encoding:UTF-16BE	String encoding from the UTF encoding family, see [ISO/IEC 10646]
UTF-16LE	@Encoding:UTF-16LE	String encoding from the UTF encoding family, see [ISO/IEC 10646]
UTF-16	@Encoding:UTF-16	String encoding from the UTF encoding family, see [ISO/IEC 10646]
BIN	@Encoding:BIN	Simple radix-based string encoding for binary-dump strings
OCT	@Encoding:OCT	Simple radix-based string encoding for octal-dump strings
HEX	@Encoding:HEX	Simple radix-based string encodingfor hexadecimal-dump strings

Order Relation

Encoding values may occur as operands of comparisons. For this case, the following order relation is defined. Started with the lowest value US-ASCII = 0:

US-ASCII < ISO-8859-1 < UTF-8 < UTF-16BE < UTF-16LE < UTF-16 < BIN < OCT < HEX

Literal

The syntax for Literals for complex data types will be used, where the member value is one of the values in the list.

@Encoding:US-ASCII|ISO-8859-1|UTF-8|UTF-16BE|UTF-16LE|UTF-16|BIN|OCT|HEX

Core Conversion

The following table shows the rules for conversion to another data type:

Conversion	Result	Sample
ToBoolean	Undefined (should not be used)
ToInteger	Returns the index of the value in the Encodings enumeration (smallest index is 0)	Integer val = ToInteger(@Encoding:US-ASCII); // Returns 0
ToFloat	Undefined (should not be used)
ToString	Returns the name of the enumeration value	String s = ToString(@Encoding:US-ASCII); // Returns "US-ASCII"
ToByteField	Undefined (should not be used)

Sample

StringUtil.Encoding EncodingVariable = @Encoding:US-ASCII;
