Namespace: PdfSharp.Pdf.Internal
An encoder for raw strings. The raw encoding is simply the identity relation between characters and bytes. PDFsharp internally works with raw encoded strings instead of byte arrays because strings are much more handy than byte arrays.
public sealed class RawEncoding : System.Text.Encoding, System.ICloneable
Inheritance Object → Encoding → RawEncoding
Implements ICloneable
Remarks:
Raw encoded strings represent an array of bytes. Therefore a character greater than 255 is not valid in a raw encoded string.
