在Python中遇到“cannot convert unicode string to 'str' implicitly”这类错误,通常发生在Python 2环境中。这是因为Python 2区分了unicode和str两种字符串类型,且它们之间不能直接隐式转换。以下是对你问题的详细解答: 理解问题原因: 在Python 2中,unicode类型表示一个包含Unicode字符的字符串,而str类型表示一个字...
VC++里面定义字符串的时候,用_T来保证兼容性。VC++支持ascii和unicode两种字符类型,用_T可以保证从ascii编码类型转换到unicode编码类型的时候,程序不需要修改。 如果将来你不打算升级到unicode,那么也不需要_T。 _t("hello world") 在ansi的环境下,它是ansi的,如果在unicode下,那么它将自动解释为双字节字符串,既...
1. 使用_T()实现ASCII与UNICODE自动转换 2. 在使用字符串的使用 T"Hello world"或者L"hello world" 3. 设置Character Set为Use Multi-Byte Character Set
vs2008下cannot convert parameter 1 from 'LPCTSTR' to 'const char *'的解决方法 1. 使用_T()实现ASCII与UNICODE自动转换 2. 在使用字符串的使用 T"Hello world"或者L"hello world" 3. 设置Character Set为Use Multi-Byte Character Set
var = [tuple(s.encode('ascii', 'replace') for s in t) for t in var] Basically this loops over every tuple in var, takes every unicode string from that tuple and calls encode() on that unicode string. But you should really read this: Convert a Unicode string to a string in Pyth...

A Unicode file in UTF-8 format. A Unicode file in UTF-16 format. A file in some other character encoding (for example, ASCII) that has as its very first bytes the UTF-7 does not use the Byte Order Mark. Also, UTF-7 converts the special XML character < to +ADw, ...
This is a definite bug, involving non-ASCII (but proper Unicode) file names, irrespective of character length; I'm pretty sure it will be resolved soon, in the meantime my workaround is to ASCII-ize the file names upon creation (so, say, "Ελλάς.pdf" becomes "Hellas.pdf". ...
error C2664: 'CWnd::MessageBoxW' : cannot convert parameter 1 from 'const char [12]' to 'LPCTSTR' What am I doing wrong? Problem This error message means that you are trying to pass a multi-byte string (const char [12]) to a function which expects a unicode string (LPCTSTR). The ...
