On translating inches

[YauHsien]

Though some escape-sequece characters was maintained, I found an unhandled case.

In some game where body measurements was discussed, the inch symbol, such as 5'6", was used. The script was written as followings:

# Some translation case:

     # mc "The body measurement is 5'6\"."
     mc ""

It will be translated as the following:

     mc "身體度量為 5'6\\"."

Then in my opinion, the escape-sequence case \" => \" should be handled as distinguished with cases " => \" and \ => \\.
