R: Check If a Data Stream Is Possibly in UTF16 or UTF32

stri_enc_isutf16be {stringi} | R Documentation

## 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). 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.

### Value

Returns a logical vector.
