On 32-bit architectures, typeof(c) will be Int32. You can easily convert a Char to its integer value, i.e. 'x': ASCII/Unicode U+0078 (category Ll: Letter, lowercase) to optimize operations for other text encodings.) Here is how Char values are input and shown: julia> c = 'x' (Julia packages may define other subtypes of AbstractChar, e.g.
#Ms access substring code#
This allows for efficient indexing into strings by the byte index of an encoded representation rather than by a character index, which cannot be implemented both efficiently and simply for variable-width encodings of Unicode strings.Ī Char value represents a single character: it is just a 32-bit primitive type with a special literal representation and appropriate arithmetic behaviors, and which can be converted to a numeric value representing a Unicode code point. Conceptually, a string is a partial function from indices to characters: for some index values, no character value is returned, and instead an exception is thrown.To construct a different string value, you construct a new string from parts of other strings. As in Java, strings are immutable: the value of an AbstractString object cannot be changed.The built-in Char subtype of AbstractChar is a 32-bit primitive type that can represent any Unicode character (and which is based on the UTF-8 encoding). Like C and Java, but unlike most dynamic languages, Julia has a first-class type for representing a single character, called AbstractChar.If you define a function expecting a string argument, you should declare the type as AbstractString in order to accept any string type. All string types are subtypes of the abstract type AbstractString, and external packages define additional AbstractString subtypes (e.g.(A transcode function is provided to convert to/from other Unicode encodings.)

This supports the full range of Unicode characters via the UTF-8 encoding.
The characters that English speakers are familiar with are the letters A, B, C, etc., together with numerals and common punctuation symbols. Of course, the real trouble comes when one asks what a character is. Strings are finite sequences of characters.
