encoded_text_to_latex {tools} | R Documentation |
Translate non-ASCII characters in text to LaTeX escape sequences.
encoded_text_to_latex(x, encoding = c("latin1", "latin2", "latin9", "UTF-8", "utf8"))
x |
a character vector. |
encoding |
the encoding to be assumed. "latin9" is
officially ISO-8859-15 or Latin-9, but known as latin9 to LaTeX's
inputenc package. |
Non-ASCII characters in x
are replaced by an appropriate LaTeX
escape sequence, or ?
if there is no appropriate sequence.
Even if there is an appropriate sequence, it may not be supported by
the font in use. Hyphen is mapped to \-
.
A character vector of the same length as x
