When enabled, the RecoStar recognition engine attempts to resolve uncertain characters on the basis of their context. This is useful when distinguishing between characters such as the number 1 and the letter l.

For example, assume that the recognition engine reads te1l. Logical context resolves this to tell because it is less likely that the number one would be embedded in letters. Do not use logical context if you want to read words that include a combination of alphabetic and numeric characters, such as Abc123def.
