Check If a Data Stream Is Possibly in UTF16 or UTF32

Description

These functions detect whether a given byte stream is valid UTF-16LE, UTF-16BE, UTF-32LE, or UTF-32BE.

Usage

stri_enc_isutf16be(str)

stri_enc_isutf16le(str)

stri_enc_isutf32be(str)

stri_enc_isutf32le(str)

Arguments

str

character vector, a raw vector, or a list of raw vectors

Details

These functions are independent of the way R marks encodings in character strings (see Encoding and stringi-encoding). Most often, these functions act on raw vectors.

A result of FALSE means that a string is surely not valid UTF-16 or UTF-32. However, false positives are possible.

Also note that a data stream may be sometimes classified as both valid UTF-16LE and UTF-16BE.

Value

Returns a logical vector.
