Doesn't the parameter of Table::GetDefinition need to be std::wstring?

[SatoruGUNJI]

The definition XML document is UTF-8:

<?xml version="1.0" encoding="UTF-8"?>
<DataElement xmlns:esri="http://www.esri.com/schemas/ArcGIS/10.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="esri:DEFeatureClass">
 ...

When the definition contains Japanese strings, these characters are garbled.

Can you send me example containing Japanese strings.

All XML data in the File Geodatabase API is in the form of a UTF-8 encoded string, therefore using std::wstring is not appropriate.  UTF-8 is a variable length Unicode character encoding, but wstring is a wide character, or UTF-16, Unicode character encoding.

Unfortunately, C++ does not have built in support for UTF-8 encoded strings.  Because of this, if you need to read or print a UTF-8 encoded string, you must first convert it to another character encoding, such as wchar_t (also known as UTF-16).  The Windows run time library provides a function for this purpose: MultiByteToWideChar.  Be sure to pass �??CP_UTF8�?� as the value of the first parameter.

Thank you very much for advice.
I will test MultiByteToWideChar.

[SatoruGUNJI]

MultiByteToWideChar works fine.
I will control these XML in program. Does Esri have the suggested XML parser and samples?

[LanceShipman]

We are using libXml. Use whatever you find convenient.

Thank you for information.
I am using the Xerces. This can get the Geodatabase XML properties.
