⚠️There's a newer version (1.8.7) of this package.Take me there.

stringi (version 0.1-25)

Character string processing facilities

Description

stringi allows for very 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 a platform-independent functionality known to Java, Perl, Python, PHP and Ruby programmers.
