stringi-search-fixed

String searching facilities described in this very man page
provide a way to locate a specific piece of
text. Note that locale-sensitive searching, especially
on a non-English language text, is a much more complex process
than it seems at the first glance.

stringi allows for fast, correct, consistent,
    and convenient character string/text processing in each locale
    and any native encoding. Thanks to the use of the ICU library,
    the package provides R users with platform-independent functions
    known to Java, Perl, Python, PHP and Ruby programmers.

stringi-search-fixed function

The Knuth-Morris-Pratt search algorithm, with worst time complexity of
O(n+p) (<code>n == length(str)</code>, <code>p == length(pattern)</code>)
is utilized (with some tweaks for very short search patterns).
For natural language processing, however, this is not what
you probably want. It is because a bitwise match will
not give correct results in cases of:
<ol><li>accented letters;</li><li>conjoined letters;</li><li>ignorable punctuation;</li><li>ignorable case,</li></ol>

to Unicode is done as usual.</p>
