- A string may be constructed either from a C string, (some number of copies of)
- a single character or a wide (Unicode) string. For all constructors (except the
- default which creates an empty string) there is also a corresponding assignment
- operator.

- @li wxString()
- @li operator=()

- The MakeXXX() variants modify the string in place, while the other functions
- return a new string which contains the original text converted to the upper or
- lower case and leave the original string unchanged.

- @li MakeUpper()
- @li Upper()
- @li MakeLower()
- @li Lower()
-
- Many functions below take a character index in the string. As with C
- strings and arrays, the indices start from 0, so the first character of a
- string is string[0]. An attempt to access a character beyond the end of the
- string (which may even be 0 if the string is empty) will provoke an assert
- failure in @ref overview_debugging "debug build", but no checks are
- done in release builds.
- This section also contains both implicit and explicit conversions to C style
- strings. Although implicit conversion is quite convenient, you are advised
- to use wc_str() for the sake of clarity.

- The default comparison function Cmp() is case-sensitive and
- so is the default version of IsSameAs(). For case
- insensitive comparisons you should use CmpNoCase() or
- give a second parameter to IsSameAs. This last function is may be more
- convenient if only equality of the strings matters because it returns a boolean
- @true value if the strings are the same and not 0 (which is usually @false
- in C) as Cmp() does.
- Matches() is a poor man's regular expression matcher: it only understands
- '*' and '?' metacharacters in the sense of DOS command line interpreter.
- StartsWith() is helpful when parsing a line of text which should start
- with some predefined prefix and is more efficient than doing direct string
- comparison as you would also have to precalculate the length of the prefix.

- The string provides functions for conversion to signed and unsigned integer and
- floating point numbers. All functions take a pointer to the variable to
- put the numeric value in and return @true if the @b entire string could be
- converted to a number.

- functions.
-

-
- Both formatted versions (Printf/() and stream-like insertion operators
- exist (for basic types only). Additionally, the Format() function allows

- @li Printf()

- The following functions are deprecated. Please consider using new wxWidgets 2.0
