```

### Parameters

**** (\[Rune]\(/engine/6000.7/script-reference/unity/collections/unicode/rune)): Outputs the character read. If the read fails, outputs [Unicode.ReplacementCharacter](/engine/6000.7/script-reference/unity/collections/unicode/replacementcharacter.md).**** (\[byte\*]\(https\://learn.microsoft.com/dotnet/api/system.byte)): The buffer of bytes to read.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): Reference to a byte index into the buffer. If the read succeeds, index is incremented by the size in bytes of the character read. If the read fails, index is incremented by 1.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The size in bytes of the buffer. Used to check that the read is in bounds.

### Returns

| Type                                                                                    | Description                                                                                                                                                                                                                                                                                                                                                        |
