與提升區域設置區域設置特定的to_lower問題

Question

我用的boost ::區域:: to_upper做具體的語言環境上，外殼按照升壓現場試驗頁http://www.boost.org/doc/libs/1_50_0/libs/locale/doc/html/conversions.html

的文字，說明我應該能夠在'grüßEN'上使用boost :: locale :: to_upper並得到結果'GRÜSSEN' - 這是正確的語言環境特定的大寫版本（所以我相信）。

在我的測試版本中，我得到'GRÜßEN'而不是'GRÜSSEN'。

我的測試代碼如下（我使用utf8cpp檢查我的字符串實際上是UTF8）：

   boost::locale::generator gen;          
       std::locale loc= gen("de_DE.UTF-8"); 

       std::locale::global(loc); 
       cout.imbue(loc); 

       string s = "grüßEN"; 
       if (utf8::is_valid(s.begin(), s.end())){ 
        std::cout << s << " U= "<< boost::locale::to_upper(s) << std::endl; 
       } 

這是OSX（10.7.4）使用的Xcode（4.1）。我已經安裝了ICU（49_1_2），其建議選項爲-DU_USING_ICU_NAMESPACE = 0-DU_CHARSET_IS_UTF8 = 1。 ICU是在/ usr /本地/包括/ Unicode和在/usr/local/lib/libicu*.*

庫我建的boost ::區域從1_48套件這樣的：

./bjam boost.locale.iconv=off -sICU_PATH=/usr/local --with-locale stage

據https://svn.boost.org/trac/boost/ticket/6424，警告可以忽略 我從舞臺/庫複製建庫到/ usr /本地/庫（或沒有人知道更好嗎？）。

因此，據我所知，它是正確建立對ICU。我的測試代碼確實需要我鏈接到libiconv - 我會認爲這不需要，因爲我關閉了構建中的圖標？

任何人都可以爲我提供一些有關正在發生的事情的信息/我做錯了什麼，以及爲什麼我沒有按照記錄得到預期的行爲 - 或者至少有些事情要嘗試？

歡呼

所以XCODE墜毀，機上我（因爲它似乎經常這樣做），一旦我重新啓動它，並重新建造的項目，它要求ICU庫和不再需要iconv庫 - 即如預期的那樣。 我打算把這個粉筆寫到我認爲的XCODE voodoo。我會留下這個問題，因爲它至少包括如何在OSX上搭建ICU的boost語言環境。
