Patch

Brew MP port uses only the subset of ICU library to reduce the binary size. Follow the WinCE's implementation.

r- because of style errors.

> JavaScriptCore/wtf/unicode/brew/UnicodeBrew.cpp:84
> +    int remainingCharacters = 0;

remainingCharacters should be declared just before it is used.

> JavaScriptCore/wtf/unicode/brew/UnicodeBrew.cpp:85
> +    if (sourceLength <= resultLength)

You should enclose this block with {} because the block contains two physical lines.

> JavaScriptCore/wtf/unicode/brew/UnicodeBrew.cpp:88
> +    else

ditto.

> JavaScriptCore/wtf/unicode/brew/UnicodeBrew.cpp:101
> +int toUpper(UChar* result, int resultLength, const UChar* source, int sourceLength, bool* isError)

Same comments as toLower().

+= looks curious here.
  int remainingCharacters = sourceIterator < sourceEnd ? sourceEnd - sourceIterator : 0;
would be better.

Do you think we can share the implementation between BREWMP and WinCE?
Do you have an example of "UnicodeFromICU.h"? Is it a "copy" of ce_unicode.h|cpp?
(I'm not very happy with the current WinCE implementation, maybe we can do it better)

IMHO we can share the implementaions as a "UnicodeMinimalCopyOfICU". I don't think that there's something BREW specific in this files.

PS: Use "svn cp" if you copy UnicodeBrew from UnicodeWinCE. This helps when looking at the history.

> Do you think we can share the implementation between BREWMP and WinCE?

Yes, I just copied the implementation of WinCE only with minor style changes.

Yes, it is just a copy of ce_unicode.h|cpp with slight changes.

I agree. There is no Brew MP specific code in these files.

Thanks for the tip.
