Unicode Support in the C++ Editions
A How-To Guide
Date Entered: 11/11/2019 Last Updated: 11/11/2019
Unicode characters can be used in all of our editions, including the C++ editions. This KB entry will cover how to work with Unicode in the C++ editions. When working with Unicode, wide character strings should be used anytime a regular string is required.
Support for Unicode is handled differently in newer versions (2020+) than older versions. This KB covers how to work with all versions and additionally how to update old code.
Newer Versions (2020+)
In 2020 and later, Unicode support is handled with a set of header files that allow the components to work with wide character strings. To use them add the <installation directory>/include/unicode folder to your include path.
Updating old code...
To update older code only these two steps should be required:
- Update the include path to point to <installation directory>/include/unicode.
- Remove the "W" suffix from any class/type name.
Older Versions (2016-)
In 2016 and older, Unicode support is handled with a set of parallel classes that work with wide character strings. These classes have the same name as the regular classes, but with a W suffix (e.g. IPPort with Unicode support is IPPortW).
Examples
These examples are functionally equivalent.

mySFTP sftp;
sftp.SetSSHUser((LPWSTR)L"user");
sftp.SetSSHPassword((LPWSTR)L"password");
sftp.SSHLogon((LPWSTR)L"sftp.server.com", 22);
sftp.ListDirectory();
sftp.SSHLogoff();
