 Text
-~~~~
+----
+
+The Text type represents Unicode character strings, in a time and space-efficient manner. This package provides text processing capabilities that are optimized for performance critical use, both in terms of large data quantities and high speed.

+Conversion
+----------
+
+```haskell
+class StringConv a b where
+  strConv :: Leniency -> a -> b
+
+data Leniency = Lenient | Strict
+```
+
+```haskell
+toS :: StringConv a b => a -> b
+```
+
+```haskell
+toSL :: StringConv a b => a -> b
+```
+
+*Example*:
+
+```haskell
+a :: LByteString
+a = "Einstein"
+
+b :: Text
+b = "Feynmann"
+
+c :: ByteString
+c = "Schrödinger"
+
+example1 :: ByteString
+example1 = toS b
+
+example2 :: Bool
+example2 = (a == toS b) && (toS b == c)
+```
