/**
|
||
|
|
* ICU-internal class CStr, a small helper class to facilitate passing UnicodeStrings
|
||
|
|
* to functions needing (const char *) strings, such as printf().
|
||
|
|
*
|
||
|
|
* It is intended primarily for use in debugging or in tests. Uses platform
|
||
|
|
* default code page conversion, which will do the best job possible,
|
||
|
|
* but may be lossy, depending on the platform.
|
||
|
|
*
|
||
|
|
* If no other conversion is available, use invariant conversion and substitue
|
||
|
|
* '?' for non-invariant characters.
|
||
|
|
*
|
||
|
|
* Example Usage:
|
||
|
|
* UnicodeString s = whatever;
|
||
|
|
* printf("%s", CStr(s)());
|
||
|
|
*
|
||
|
|
* The explicit call to the CStr() constructor creates a temporary object.
|
||
|
|
* Operator () on the temporary object returns a (const char *) pointer.
|
||
|
|
* The lifetime of the (const char *) data is that of the temporary object,
|
||
|
|
* which works well when passing it as a parameter to another function, such as printf.
