# CharConfidence Property of the PlainText Object

> CharConfidence property of the PlainText Object in the ABBYY FineReader Engine API — Returns the recognition confidence for the specified character (main recognition variant); intended for comparing variants of the same character, not a general quality measure.

This property returns the recognition confidence for the specified character. This is the confidence of the main (selected) recognition variant.

Confidence estimates the accuracy of a recognition variant. It should not be understood as a general recognition quality measure: the only safe use of confidence is for comparing recognition variants of the same character. The characters extracted from the source PDF file without recognition have confidence set to 55.

## Syntax

### C++

```cpp theme={null}
HRESULT get_CharConfidence(
   int  Index,
   int* Result
);
```

### C\#

```csharp theme={null}
int get_CharConfidence( int Index );
```

### Visual Basic .NET

```vb theme={null}
Property CharConfidence(Index As Integer) As Integer
```

## Parameters

Index

\[in] This parameter specifies the index of the specified symbol in the recognized text.

Result

\[out, retval] A pointer to int variable that receives the value of this property.
