* Update index.properties

* Update index.properties

Whenever you are using MessageFormat you should be aware that the single quote character (') fulfils a special purpose inside message patterns. The single quote is used to represent a section within the message pattern that will not be formatted. A single quote itself must be escaped by using two single quotes ('').
