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 noticeable 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.
    • + *
+ * + *

Formatting and Parsing Specification

+ * + * General printf format:
+ * %[format modifier][width][.precision][type modifier][format] + * + * General scanf format:
+ * %[*][format modifier][width][type modifier][format] + * + + + + + + + + + + + + + + + + + + + + + +

%EdoublefloatScientific with an uppercase exponent

%GdoublefloatUse %E or %f for best format

%fdoublefloatSimple floating point without the exponent
%Xint32_tint32_tustdio special uppercase hex radix formatting
%xint32_tint32_tustdio special lowercase hex radix formatting
%dint32_tint32_tDecimal format
%iint32_tint32_tSame as %d

+By default, only one char is written.
%SUChar *UChar *Null terminated UTF-16 string
%CUCharUChar16-bit Unicode code unit
+When width is specified for scanf, this acts like a non-NULL-terminated UChar * string
+By default, only one codepoint is written.
%[] UChar *Null terminated UTF-16 string which contains the filtered set of characters specified by the UnicodeSet

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);
+
