How-to: manage unicode strings into Hoops Publish

In Hoops Publish API, every character string must be given as A3DUTF8Char*. However, when dealing with foreign characters such as Japanese or Russian ones, they are initially given as Unicode strings.

This article is showing how to convert Unicode strings to UTF8Char strings, to display foreign characters in a PDF file.

Here is an example with a Japanese character string:

1. Allocate the destination string

2. Convert the Unicode string to the UTF8 one
   

   wchar_t sString[] = L"新細明體";
   A3DUTF8Char* pcDestString = new A3DUTF8Char[500];
   A3DMiscUnicodeToUTF8((const A3DUTF8Char*)sString, pcDestString );

Now pcDestString can be used in any function or field data requiring a UTF8 string. And the Japanese characters will be displayed correctly in the PDF file.
