ICU Selection
When installing the Internationalization Module, use a bundled ICU installation provided by Rogue Wave or an ICU already installed on your machine.
For a bundled ICU installation, choose a version from the dropdown.
NOTE: ICU 58.2 is included for compatibility with C++03, however there are a number of known security vulnerabilities in ICU 58.2. It is recommended that users migrate to C++11 or higher, and the latest supported version of ICU.
Choosing to use a custom ICU installation prompts you to specify a path, see ICU Directory Path.
