Unicode stdio-like C API

- * - *

This API provides an stdio-like API wrapper around ICU's other - * formatting and parsing APIs. It is meant to ease the transition of adding - * Unicode support to a preexisting applications using stdio. The following - * is a small list of noticable differences between stdio and ICU I/O's - * ustdio implementation.

- * - *
    - *
  • Locale specific formatting and parsing is only done with file IO.
    • - *
  • u_fstropen can be used to simulate file IO with strings. - * This is similar to the iostream API, and it allows locale specific - * formatting and parsing to be used.
    • - *
  • This API provides uniform formatting and parsing behavior between - * platforms (unlike the standard stdio implementations found on various - * platforms).
    • - *
  • This API is better suited for text data handling than binary data - * handling when compared to the typical stdio implementation.
    • - *
  • You can specify a Transliterator while using the file IO.
    • - *
  • You can specify a file's codepage separately from the default - * system codepage.
    • - *

If you are using this C API instead of the ustream.h API for C++, -you can use one of the following u_fprintf examples to display a UnicodeString.

- -

-    UFILE *out = u_finit(stdout, NULL, NULL);
-    UnicodeString string1("string 1");
-    UnicodeString string2("string 2");
-    u_fprintf(out, "%S\n", string1.getTerminatedBuffer());
-    u_fprintf(out, "%.*S\n", string2.length(), string2.getBuffer());
-    u_fclose(out);
