# Reject Documents with Symbolic Content

The `SymbolicContentFilter` task calculates the proportion of symbolic characters in a document. If the proportion of symbolic characters in the document content exceeds the limit specified by the `MaxSymbolicCharactersPercent` parameter, the document is rejected.

Symbolic characters are defined as any character between U+2000 and U+2FFF.

The `SymbolicContentFilter` task can be configured as a Post task. The parameters that are passed to the task are specified in a named section of the configuration file. For example:

    [ImportTasks]
    Post0=SymbolicContentFilter:SymbolicContentFilterSettings

    [SymbolicContentFilterSettings]
    MaxSymbolicCharactersPercent=8
    OnErrorIndexerSections=IdolErrorServer
    IndexDatabase=IdolErrorReview

For information about the parameters that you can use to configure this task, refer to the Connector Framework Server Reference.
