This validation checks if both original string and its translation include the same number of period at the end of the string. Some examples:
|This is a sample.||Tämä on esimerkki||Original has period but translation does not have.|
|Browse...||Selaa||Original has three periods but translation does not have.|
|Open||Avaa.||Original does not have period but translation has.|
This validation can handle also Asian periods and different question marks used in Japanese text.
