Fold over the characters of UTF encoded OCaml string values.

Encoding guess

val encoding_guess : string -> [ `UTF_8 | `UTF_16BE | `UTF_16LE ] * bool

encoding_guess s is the encoding guessed for s coupled with true iff there's an initial BOM.

String folders

Note. Initial BOMs are also folded over.

type 'a folder = 'a -> int -> [ `Uchar of uchar | `Malformed of string ] -> 'a

The type for character folders. The integer is the index in the string where the `Uchar or `Malformed starts.

val fold_utf_8 : 'a folder -> 'a -> string -> 'a

fold_utf_8 f a s is f ( ... (f (f a 0 u₀) j₁ u₁) ... ) ... ) j_n u_n where u_i, j_i are the Unicode scalar value and the starting position of the characters in the UTF-8 encoded string s.

val fold_utf_16be : 'a folder -> 'a -> string -> 'a

fold_utf_16be f a s is f ( ... (f (f a 0 u₀) j₁ u₁) ... ) ... ) j_n u_n where u_i, j_i are the Unicode scalar value and the starting position of the characters in the UTF-16BE encoded string s.

val fold_utf_16le : 'a folder -> 'a -> string -> 'a

fold_utf_16le f a s is f ( ... (f (f a 0 u₀) j₁ u₁) ... ) ... ) j_n u_n where u_i, j_i are the Unicode scalar value and the starting position of the characters in the UTF-16LE encoded string s.
