## Escape Unicode Code Points

### Description

Escapes all Unicode (not ASCII-printable) code points.

### Usage

    stri_escape_unicode(str)

### Arguments

`str` | character vector

### Details

For non-printable and certain special (well-known, see also 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, any input string is converted to Unicode before executing the escape process.
