Escape Unicode Code Points

Generates an ASCII string where all non-printable characters and non-ASCII characters are converted to escape sequences.

Usage

stri_escape_unicode(str)

Arguments

str

character vector

Value

Returns a character vector.

Details

For non-printable and certain special (well-known, see also the R man page Quotes) ASCII characters, the following (also recognized in R) convention is used. We get \a, \b, \t, \n, \v, \f, \r, \", \', \\ or either \uXXXX (4 hex digits) or \UXXXXXXXX (8 hex digits) otherwise.

As usual in stringi, any input string is converted to Unicode before executing the escape process.
