如果 utf 8 字符不是硬编码问题,Chrome 和 Safari 处理 utf 8 的方式与 Firefox 和 IE 不同?
问答中所述
注意:问题标题已更改,如本元 将 jQuery bassistance 自动完成插件与 口音插件 一起使用,所以我有口音-免费自动完成。重音映射是这样的:
map={'À':'A', 'İ':'I'};
我对字符 I
(带有点的土耳其大写 I)有疑问。删除重音符号并转换为小写后,我得到以下代码:
("İstanbul").indexOf("is")
Firefox 和 IE 给出 0
,但 Chrome 和 Safari 给出 -1
。
charCodeAt(0)
在所有浏览器中给出相同的结果。
看来 Chrome 和 Safari 对普通的 I 和不带重音的 I 的处理方式有所不同。
编辑
再次嗨,大约 5 个月后,我终于可以为我的问题添加更多来源。
幸运的是,问题日期和我在该日期的备份可以帮助我找到源代码。
当我用 AFTER (WORKS OK) 更改代码时,BEFORE(TURKISH © BUG) 已修复。
下面我还添加了我的文档字符集(土耳其语)
我不是 unicode 专家,但如果你让我猜测“chrome vs ff”问题:
chrome 使用“源代码”处理字符,我的意思是像 \u0128
ff 用“可见字符”处理它,我的意思是“?”
之前(土耳其语我的错误)

之后(工作正常)
var charToAccentedCharClassMap = {

// J to Z
};
函数 deaccent(accentedString) { var 结果 = 重音字符串; for (charToAccentedCharClassMap 中的 var key) { 结果 = result.replace(new RegExp(charToAccentedCharClassMap[key], "g"), key); } //console.log(accentedString) 返回结果.toLowerCase(); }
函数remove_accent(str) { 返回 deaccent(str).toLowerCase(); 返回字符串; }
EDIT2 小修正(所以用户编辑了问题,但错过了他的键盘):
他将 ("伊斯坦布尔").indexOf("is") 替换为 ("istanbul").indexOf("is")
note: question title is change as discussed in this meta Q&A
I'm using the jQuery bassistance autocomplete plugin with the accent plugin, so I have accent-free autocomplete. Accent map is like this:
map={'À':'A', 'İ':'I'};
I have problems with the character İ
(turkish uppercase I with point). After I remove accents and convert to lowercase, I have this code:
("İstanbul").indexOf("is")
Firefox and IE gives 0
, but Chrome and Safari gives -1
.
charCodeAt(0)
gives the same result in all browsers.
It seems that Chrome and Safari treats the normal I and the unaccented I different.
EDIT
Hi again, after about 5 months, I can finally add more source to my question.
Fortunately question date and my backups at that date helps me find source code.
BEFORE(TURKISH İ BUG) was fixed when I change my code with AFTER (WORKS OK).
Below I added also my document charshet(which is turkish)
I am not unicode expert, but if you let me guess about the "chrome vs ff" issue:
chrome handles the characther with "source code", I mean like \u0128
ff handles it with "visible characher", I mean like "İ"

EDIT2 little correction (SO user edited question but misses İ his keyboard):
He replaces ("İstanbul").indexOf("is") by ("istanbul").indexOf("is")

小写的“I”是“ı”。这就是这里发生的事情吗?
编辑:
可能为时已晚,但我现在记得我遇到了一个非常相似的情况,其中“@”与“@”不同,因为它是不同的unicode字符。我通过硬编码字符串中的 Unicode 数字解决了这个问题,如“
\u0040
”Lowercase 'I' is 'ı'. Is that what is happening here?
EDIT:
Probably too late, but I remember now I encountered a very similar case where "@" was different from "@" because it was a different unicode character. I solved it by hardcoding the Unicode number in the string like "
\u0040
"
