stri_unescape_unicode: Un-escape All Escape Sequences¶
Description¶

Usage¶
stri_unescape_unicode(str)
Arguments¶
|
character vector |
Details¶
Uses ICU facilities to un-escape Unicode character sequences.
The following ASCII standard escapes are recognized: \a
, \b
, \t
, \n
, \v
, \?
, \e
, \f
, \r
, \"
, \'
, \\
.
Moreover, the function understands the following ones: \uXXXX
(4 hex digits), \UXXXXXXXX
(8 hex digits), \xXX
(1-2 hex digits), \ooo
(1-3 octal digits), \cX
(control-X; X is masked with 0x1F). For \xXX
and \ooo
, beware of non-valid UTF-8 byte sequences.
Note that some versions of R on Windows cannot handle characters defined with \UXXXXXXXX. We are working on that.
