UTF-8 Text Formatting

Format a character object for UTF-8 printing.

Usage
utf8_format(x, trim = FALSE, chars = NULL, justify = "left",
            width = NULL, na.encode = TRUE, quote = FALSE,
            na.print = NULL, print.gap = NULL, utf8 = NULL, ...)
Arguments
x

character object.

trim

logical scalar indicating whether to suppress padding spaces around elements.

chars

integer scalar indicating the maximum number of character units to display. Wide characters like emoji take two character units; combining marks and default ignorables take none. Longer strings get truncated and suffixed or prefixed with an ellipsis ("..." or "\u2026", whichever is most appropriate for the current character locale). Set to NULL to limit output to the line width as determined by getOption("width").

justify

justification; one of "left", "right", "centre", or "none". Can be abbreviated.

width

the minimum field width; set to NULL or 0 for no restriction.

na.encode

logical scalar indicating whether to encode NA values as character strings.

quote

logical scalar indicating whether to format for a context with surrounding double-quotes ('"') and escaped internal double-quotes.

na.print

character string (or NULL) indicating the encoding for NA values. Ignored when na.encode is FALSE.

print.gap

non-negative integer (or NULL) giving the number of spaces in gaps between columns; set to NULL or 1 for a single space.

utf8

logical scalar indicating whether to format for a UTF-8 capable display (ASCII-only otherwise), or NULL to format for output capabilities as determined by output_utf8().

...

further arguments passed from other methods. Ignored.

Details

utf8_format formats a character object for printing, optionally truncating long character strings.

Value

A character object with the same attributes as x but with Encoding set to "UTF-8" for elements that can be converted to valid UTF-8 and "bytes" for others.
