These functions detect whether a given byte stream is valid UTF-16LE, UTF-16BE, UTF-32LE, or UTF-32BE.
stri_enc_isutf16be(str)stri_enc_isutf16le(str)
stri_enc_isutf32be(str)
stri_enc_isutf32le(str)
character vector, a raw vector, or
a list of raw vectors
Returns a logical vector.
These functions are independent of the way R marks encodings in character strings (see Encoding and stringi-encoding). Anyway, most often, you will provide input data as raw vectors here.
Negative answer means that a string is surely not in valid UTF-16 or UTF-32. Positive result does not mean that we should be absolutely sure.
Also, note that sometimes a data stream may be classified as both valid UTF-16LE and UTF-16BE.
