-- Provides UTF-8 aware string functions implemented in pure lua: | |

-- * string.utf8reverse(s) | |
-- * string.utf8char(unicode) | |
-- * string.utf8unicode(s, i, j) | |
-- * string.utf8gensub(s, sub_len) | |

* Fancy ID generator that creates 20-character string identifiers with the following properties: | |
* | |
* 1. They're based on timestamp so that they sort *after* any existing ids. | |
* 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs. | |
* 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly). | |
* 4. They're monotonically increasing. Even if you generate more than one in the same timestamp, the | |
* latter ones will sort after the former ones. We do this by using the previous random bits |
