楼主因为学艺不精,用串了名词,被你指出来了。
你因为眼神不济,看串了名词,被俺指出来了。
就这么简单。
回答你第一个问题,摘自
http://unicode.org/faq/utf_bom.htmlQ: What is a UTF?
A: A Unicode transformation format (UTF) is an algorithmic mapping from
every Unicode code point (except surrogate code points) to a unique byte
sequence. The ISO/IEC 10646 standard uses the term “UCS transformation
format” for UTF; the two terms are merely synonyms for the same concept.
Each UTF is reversible, thus every UTF supports lossless round tripping:
mapping from any Unicode coded character sequence S to a sequence of bytes
and back will produce S again. To ensure round tripping, a UTF mapping must
also map all code points that are not valid Unicode characters to unique
byte sequences. These invalid code points are the 66 noncharacters
(including FFFE and FFFF), as well as unpaired surrogates.
The SCSU compression method, even though it is reversible, is not a UTF
because the same string can map to very many different byte sequences,
depending on the particular SCSU compressor. [AF] & [MD]
你可以自己判断一下楼主贴出的编码有没有跟这个定义相抵触。第二个问题俺就不回答
了。

: 请问有utf码这个概念么?原文给出的那个urlencode叫做utf码?
