-# utf8.lua
-one-file pure-lua 5.1 regex library
-
-This library _is_ the simple way to add utf8 support into your application.
-
-Some examples from http://www.lua.org/manual/5.1/manual.html#5.4 :
-```Lua
-local utf8 = require "utf8"
-
-local s = "hello world from Lua"
-for w in string.gmatch(s, "%a+") do
-    print(w)
-end
---[[
-hello
-world
-from
-Lua
-]]--
-
-s = "Привет, мир, от Lua"
-for w in utf8.gmatch(s, "[^%p%d%s%c]+") do
-    print(w)
-end
---[[
-Привет
-мир
-от
-Lua
-]]--
-
-local t = {}
-s = "from=world, to=Lua"
-for k, v in string.gmatch(s, "(%w+)=(%w+)") do
-    t[k] = v
-end
-for k,v in pairs(t) do
-    print(k,v)
-end
---[[
-to	Lua
-from	world
-]]--
-
-t = {}
-s = "从=世界, 到=Lua"
-for k, v in utf8.gmatch(s, "([^%p%s%c]+)=([^%p%s%c]+)") do
-    t[k] = v
-end
-for k,v in pairs(t) do
-    print(k,v)
-end
---[[
-到	Lua
-从	世界
-]]--
-
-local x = string.gsub("hello world", "(%w+)", "%1 %1")
-print(x)
---hello hello world world
-
-x = utf8.gsub("Ahoj světe", "([^%p%s%c]+)", "%1 %1")
-print(x)
---Ahoj Ahoj světe světe
-
-x = string.gsub("hello world", "%w+", "%0 %0", 1)
-print(x)
---hello hello world
-
-x = utf8.gsub("Ahoj světe", "[^%p%s%c]+", "%0 %0", 1)
-print(x)
---Ahoj Ahoj světe
-
-x = string.gsub("hello world from Lua", "(%w+)%s*(%w+)", "%2 %1")
-print(x)
---world hello Lua from
-
-x = utf8.gsub("γεια κόσμο από Lua", "([^%p%s%c]+)%s*([^%p%s%c]+)", "%2 %1")
-print(x)
---κόσμο γεια Lua από
-```
-Notice, there are some classes that can work only with latin(ASCII) symbols,
-for details see: https://github.com/Stepets/utf8.lua/blob/master/utf8.lua#L470
-
-Of course you can do this trick:
-```Lua
-for k,v in pairs(utf8) do
-        string[k] = v
-end
-```
-But this can lead to very strange errors. You were warned.
-
-A little bit more interesting examples:
-```Lua
-local utf8 = require 'utf8'
-for k,v in pairs(utf8) do
-        string[k] = v
-end
-
-local str = "пыщпыщ ололоо я водитель нло"
-print(str:find("(.л.+)н"))
--- 8	26	ололоо я водитель 
-
-print(str:gsub("ло+", "보라"))
--- пыщпыщ о보라보라 я водитель н보라	3
-
-print(str:match("^п[лопыщ ]*я"))
--- пыщпыщ ололоо я
-```
