    find_character(string,char) returns integer Description Returns the position of the start of the first occurrence of the character char in string. If the character is not found most of these routines return an invalid index value – -1 where indexes are 0-based, 0 where they are 1-based – or some value to be interpreted as Boolean FALSE.

    en.wikipedia.org/wiki/String_literal

    A string literal or anonymous string is a literal for a string value in the source code of a computer program. Modern programming languages commonly use a quoted sequence of characters, formally "bracketed delimiters", as in x = "foo" , where , "foo" is a string literal with value foo .

  4. Comparison of Unicode encodings - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Unicode...

    A UTF-8 file that contains only ASCII characters is identical to an ASCII file. Legacy programs can generally handle UTF-8 encoded files, even if they contain non-ASCII characters. For instance, the C printf function can print a UTF-8 string because it only looks for the ASCII '%' character to define a formatting string. All other bytes are ...

    If an identifier is needed which would be the same as a reserved keyword, it may be prefixed by an at sign to distinguish it. For example, @out is interpreted as an identifier, whereas out as a keyword. This syntax facilitates reuse of .NET code written in other languages.

    With this it is possible to encode 128 (i.e. 2 7) unique values (0–127) to represent the alphabetic, numeric, and punctuation characters commonly used in English, plus a selection of Control characters which do not represent printable characters. For example, the capital letter A is represented in 7 bits as 100 0001 2, 0x41 (101 8) , the ...

    The identity of any character is determined by its properties stated in the Unicode Character Database. For example, the contiguous range of 32 noncharacter code points U+FDD0..U+FDEF share none of the properties common to the other characters in the Arabic Presentation Forms-A block, that they are certainly not Arabic script characters or ...
