| Default |
Gets the default UnicodeFunctions instance with built-in Unicode support. |
| Empty |
Gets a reference to the empty UnicodeFunctions instance with no callbacks set. |
| Handle |
Gets or sets the handle to the underlying native object. (Inherited from NativeObject) |
| IsImmutable |
Gets a value indicating whether this Unicode functions instance is immutable. |
| Parent |
Gets the parent Unicode functions that this instance inherits from. |
Methods
| Name | Description |
|---|---|
| Dispose() |
Releases all resources used by this NativeObject. (Inherited from NativeObject) |
| Dispose(Boolean) |
Releases the unmanaged resources used by the UnicodeFunctions and optionally releases the managed resources. |
| DisposeHandler() |
Releases the unmanaged resources used. |
| GetCombiningClass(Int32) |
Gets the canonical combining class of the specified Unicode code point. |

| GetMirroring(UInt32) |
Gets the mirrored code point for bidirectional text rendering. |
| GetScript(Int32) |
Gets the script of the specified Unicode code point. |
| GetScript(UInt32) |
Gets the script of the specified Unicode code point. |
| MakeImmutable() |
Makes this Unicode functions instance immutable, preventing further modifications. |
| SetCombiningClassDelegate(CombiningClassDelegate, ReleaseDelegate) |
Sets the callback for retrieving the canonical combining class of a Unicode code point. |
| SetComposeDelegate(ComposeDelegate, ReleaseDelegate) |
Sets the callback for composing two Unicode code points into a single code point. |
| SetDecomposeDelegate(DecomposeDelegate, ReleaseDelegate) |
Sets the callback for decomposing a Unicode code point into two code points. |
| SetGeneralCategoryDelegate(GeneralCategoryDelegate, ReleaseDelegate) |
