Programming With the Text Encoding Conversion ManagerBased on the given text encoding specification, creates and returns a Unicode converter object containing information required for converting strings from the specified non-Unicode encoding to Unicode.
pascal OSStatus CreateTextToUnicodeInfoByEncoding (
This function offers you an easier, alternative way to create a Unicode converter than with the function CreateTextToUnicodeInfo because you do not need to create a Unicode mapping structure. You simply specify the text encoding of the source text. However, this method is less efficient because the text encoding parameter must be resolved internally into a Unicode mapping.
Using this function, you cannot specify a version of Unicode, so a default version of Unicode is used; 16-bit format is assumed.
You pass a Unicode converter object returned from CreateTextToUnicodeInfoByEncoding to the function ConvertFromTextToUnicode or ConvertFromPStringToUnicode to identify the information to be used for the conversion. These two functions modify the contents of the Unicode converter object.
You pass a Unicode converter object returned from CreateTextToUnicodeInfoByEncoding to the function TruncateForTextToUnicode to identify the information to be used to truncate the string. This function does not modify the contents of the Unicode converter object.
If you are converting the text stream to Unicode as an intermediary encoding, and then from Unicode to the final destination encoding, you use the function CreateUnicodeToTextInfo to create a Unicode converter object for the second part of the process.
