Check If a Data Stream Is Possibly in UTF-16 or UTF-32
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)
str |
character vector, a raw vector, or
a list of |
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.
Returns a logical vector.
