To palliate this problem, some getters in the library revCapture must return possibly UTF-8 encoded names (such as the codecs) to allow the script writer to set them.

In the same idea, some setters can be given UTF-8 encoded strings.

Affected getters:

- revCaptureListAudioInputs

- revCaptureListVideoInputs

- revCaptureGetAudioInput

- revCaptureGetVideoInput

- revCaptureGetPreviewImage

- revCaptureListAudioCodecs

- revCaptureListVideoCodecs

- revCaptureGetAudioCodec

- revCaptureGetVideoCodec

- revCaptureGetRecordOutput

Affected setters:

- revCaptureSetAudioInput

- revCaptureSetVideoInput

- revCaptureSetPreviewImage

- revCaptureSetAudioCodec

- revCaptureSetVideoCodec

- revCaptureSetRecordOutput
