PC版ゲーム--cocos 2 d-x中国語の文字化けし解決方法(GBKからUTF-8コード)とそのfatal error:iconviconv.h:No such file or directory問題
10048 ワード
<1>原因:これはVCがGBK符号化を採用し、cococos 2 d-xがUTF-8符号化を採用し、符号化方法が一致しないためである.
<2>解決策:
libiconvを追加します.lib.手順:参照-->構成プロパティ-->コネクタ-->入力-->依存項目を追加libiconvを追加します.lib
<3>iconv.hはClassesの下に追加されます.そのうちiconv.hの内容は以下の通りである.
<4>ファイルを追加するTool.hとToolcpp、内容は以下の通りです.

/* We would like to #include any system header file which could define
iconv_t, 1. in order to eliminate the risk that the user gets compilation
errors because some other system header file includes /usr/include/iconv.h
which defines iconv_t or declares iconv after this file, 2. when compiling
for LIBICONV_PLUG, we need the proper iconv_t type in order to produce
binary compatible code.
But gcc's #include_next is not portable. Thus, once libiconv's iconv.h
has been installed in /usr/local/include, there is no way any more to
include the original /usr/include/iconv.h. We simply have to get away
without it.
Ad 1. The risk that a system header file does
#include "iconv.h" or #include_next "iconv.h"
is small. They all do #include <iconv.h>.
Ad 2. The iconv_t type is a pointer type in all cases I have seen. (It
has to be a scalar type because (iconv_t)(-1) is a possible return value
from iconv_open().) */

注意1つの問題:unicodeとutf 8が一緒にミキシングされた場合、setTextを実行することができなくなり、表示できなくなる.例:btn->setTitleText(toStr(" %i ",info->getMaxNum())->getCString());
info->getMaxNum()はサーバから読み出すutf 8符号化であり、vs自体が持つフォントは「サイン」、「次」はUnicodeであるため、全体が一緒になると文字化けしてしまう.
ソリューション:string signStr = a2u(" "); signStr += CCString::createWithFormat("%i", info->getMaxNum())->getCString(); signStr += a2u(" ");
