Abstract
Techniques and solutions are provided for determining the validity of encoded data. Data encoding techniques associated with a particular format can encode characters as a sequence of bytes, where the bytes can be of particular types. Particular sequences of byte types can be valid or invalid using a given encoding format. Lookup tables can be defined to examine bytes in a byte sequence to determine whether the sequence is valid or invalid. In a particular example, results of lookup operations can produce a result in the form of a sequence of bits, where values of the bits can be used to identify that a sequence is invalid, as well a particular type of encoding error. The techniques can be implemented in ways that are particularly efficient for a computing system, such as implementing lookup operations using SIMD (“Single Instruction, Multiple Data”) techniques.
