PlainText is a Java 1.4 graphical (GUI) application to convert Unicode characters to plain text characters, for example, to convert left and right quotation marks into plain quotes for web pages.

If a string contains either the unicode character \u2028 (line separator) or \u2029 (paragraph separator), calling as_json or to_json on the string will output JSON that cannot be parsed as Javascript ...

Java gives you the ability to dynamically create strings. Even after you set the string value, you can add more characters to the string value throughout the code.

Even though the introduction of Unicode technically solved this problem, you can still encounter situations in which some or all of your Unicode characters will not display properly in Java programs.

The String.split method is not limited to splitting on a single character. In the next example, I use the three characters of the Groovy Spaceship Operator (<=>) as the token (and it works fine).
