/*
|
|
The following is a small list as to what is currently wrong/suggestions for
|
|
ustdio.
|
|
|
|
* The const char* format specification should use unescape
|
|
* ufile_locale2codepage should not be used. Using one of putil.c's functions
|
|
would be better or some new API would be better.
|
|
* %D and %T printf uses the current timezone, but the scanf version uses GMT.
|
|
* %p should be deprecated. Pointers are 2-16 bytes big and scanf should
|
|
really read them.
|
|
* The format specification should use int32_t and ICU type variants instead of
|
|
the compiler dependent int.
|
|
* We should consider using Microsoft's wprintf and wscanf format
|
|
specification.
|
|
* + in printf format specification is incomplete.
|
|
* Make sure that #, blank and precision in the printf format specification
|
|
works.
|
|
* Make sure that * in the scanf format specification works.
|
|
* e and g should lowercase the scientific notation.
|
|
* E and F should uppercase the scientific notation.
|
|
* Each UFILE takes up at least 2KB. This should be really reduced.
|
|
* This library does buffering. The OS should do this for us already. Check on
|
|
this, and remove it from this library, if this is the case. Double buffering
|
|
wastes a lot of time and space.
|
|
* There is a locale cache. It needs to be cleaned up when the library unloads.
|
|
* Make sure that surrogates are supported.
|
|
* More testing is needed.
|
|
* #include <iostream> from common/unicode/unistr.h should go into a new
|
|
separate header (uios.h or ustream.h?) in the ustdio library. Plenty of
|
|
people do not use the iostream functionality for Unicode strings, and it
|
|
will vastly speed up compilation time of .cpp files for those people that
|
|
don't use it. In some cases, libraries that use ICU should not include
|
|
iostream. This new header file should also include operator<< and
|
|
operator>> for UDate (not double) and UChar *.
|
|
* fprintf/fscanf should use sprintf/sscanf in order to make testing easier.
|
|
* Testing should be done for reading and writing multi-byte encodings,
|
|
and make sure that a character that is contained across buffer boundries
|
|
works even for incomplete characters.
|
|
* Make sure that the last character is flushed when the file/string is closed.
