Measure the Character String Width
Compute the display widths of the elements of a character object.
utf8_width(x, encode = TRUE, quote = FALSE, utf8 = NULL)
x |
character object. |
encode |
whether to encode the object before measuring its width. |
quote |
whether to quote the object before measuring its width. |
utf8 |
logical scalar indicating whether to determine widths
assuming a UTF-8 capable display (ASCII-only otherwise), or
|
utf8_width returns the printed widths of the elements of
a character object on a UTF-8 device (or on an ASCII device
when output_utf8() is FALSE), when printed with
utf8_print. If the string is not printable on the device,
for example if it contains a control code like "\n", then
the result is NA. If encode = TRUE, the default,
then the function returns the widths of the encoded elements
via utf8_encode); otherwise, the function returns the
widths of the original elements.
An integer object, with the same names, dim, and
dimnames as x.
# the second element is encoded in latin-1, but declared as UTF-8
x <- c("fa\u00E7ile", "fa\xE7ile", "fa\xC3\xA7ile")
Encoding(x) <- c("UTF-8", "UTF-8", "bytes")
# get widths
utf8_width(x)
utf8_width(x, encode = FALSE)
utf8_width('"')
utf8_width('"', quote = TRUE)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
