# Ensuring the Correct Character Encoding

Subscribe supports the UTF-8 encoded character set. When you construct Subscribe objects, especially with data input by your customers (such as the data on a Web form), ensure that the strings are UTF-8 encoded.

**Note:** Most programming languages contain a built-in function that enables you to convert strings into UTF-8 encoded strings. In PHP, for example, that function is `utf8_encode()`.
