# LetterSet Property of the TextLanguage Object

This property sets up additional letter sets for the text language. Every base language included in the collection of base languages of the text language provides its own letter sets. Each word in the text is recognized using one or several base languages, and thus their letter sets are applied to this word. This property specifies the number of letter sets that are applied to every recognized word irrespectively of the base language assigned to it.

## Syntax

### C++

```cpp theme={null}
HRESULT get_LetterSet(
   TextLanguageLetterSetEnum Type,
   BSTR*                     Result
);
HRESULT put_LetterSet(
   TextLanguageLetterSetEnum Type,
   BSTR                      Value
);
```

### C\#

```csharp theme={null}
string get_LetterSet( TextLanguageLetterSetEnum Type );
void set_LetterSet(
   TextLanguageLetterSetEnum Type,
   string                    Value
);
```

### Visual Basic .NET

```vb theme={null}
Property LetterSet(Type As TextLanguageLetterSetEnum) As String
```

## Parameters

Value
