我需要将字符串HTML从混合的西里尔字母和拉丁字符转换为UNICODE。
我尝试了以下内容:
Public HTML As String
Sub HTMLsearch()
GetHTML ("http://nfs.mobile.bg/pcgi/mobile.cgi?act=3&slink=6jkjov&f1=1")
MsgBox HTML
HTML = StrConv(HTML, vbUnicode)
MsgBox HTML
End Sub
Function GetHTML(URL As String) As String
With CreateObject("MSXML2.XMLHTTP")
.Open "GET", URL, False
.Send
HTML = .ResponseText
End With
End Function
您可以看到StrConv之前和之后的内容。如果您想在文件中获取html,可以使用以下代码:
Public HTML As String
Sub HTMLsearch()
GetHTML ("http://nfs.mobile.bg/pcgi/mobile.cgi?act=3&slink=6jkjov&f1=1")
Dim path As String
path = ThisWorkbook.path & "\html.txt"
Open path For Output As #1
Print #1, HTML
Close #1
HTML = StrConv(HTML, vbUnicode)
path = ThisWorkbook.path & "\htmlUNICODE.txt"
Open path For Output As #1
Print #1, HTML
Close #1
End Sub
Function GetHTML(URL As String) As String
With CreateObject("MSXML2.XMLHTTP")
.Open "GET", URL, False
.Send
HTML = .ResponseText
End With
End Function

VBA对Unicode的支持并不是那么好。
可以处理Unicode字符串,但是您无法看到Debug.Print
或MsgBox
的实际字符 - 它们将显示为?
。
您可以设置控制面板>地区和语言> “管理”标签> "非Unicode程序的当前语言" 到"俄语"切换到不同的代码页,这将允许您在VBA消息框中查看西里尔字母而不是问号。但这只是一种美化改变。
你真正的问题在于此处。
服务器(nfs.mobile.bg)将文档发送为Content-Type: text/html
。没有关于字符编码的信息。这意味着接收器必须自己找出字符编码。
浏览器通过查看响应字节流并进行猜测来做到这一点。在您的情况下,HMTL源中存在有用的<meta http-equiv="Content-Type" content="text/html; charset=windows-1251">
标记。因此,字节流应解释为Windows-1251
,恰好是Windows中的西里尔语ANSI代码页。
所以,我们这里甚至没有Unicode!
如果没有任何其他信息,responseText
对象的XMLHTTP
属性默认为us-ascii
。西里尔字母表中的扩展字符不存在于ASCII中,因此它们将转换为实际问号并丢失。这就是为什么你不能用responseText
来做任何事情的原因。
但是,responseBody
属性中的原始字节仍然可用,Byte
属性是ADODB.Stream
的数组。
在VBA中,您必须执行与浏览器相同的操作。您必须将字节流解释为特定字符集。 ' reference: "Microsoft XML, v6.0" (or any other version)
' reference: "Microsoft ActiveX Data Objects 6.1 library" (or any other version)
Option Explicit
Sub HTMLsearch()
Dim url As String, html As String
url = "http://nfs.mobile.bg/pcgi/mobile.cgi?act=3&slink=6jkjov&f1=1"
html = GetHTML(url, "Windows-1251")
' Cyrillic characters are supported in Office, so they will appear correctly
ActiveDocument.Range.InsertAfter html
End Sub
Function GetHTML(Url As String, Optional Charset As String = "UTF-8") As String
Dim request As New MSXML2.XMLHTTP
Dim converter As New ADODB.stream
' fetch page
request.Open "GET", Url, False
request.send
' write raw bytes to the stream
converter.Open
converter.Type = adTypeBinary
converter.Write request.responseBody
' switch the stream to text mode and set charset
converter.Position = 0
converter.Type = adTypeText
converter.Charset = Charset
' read text characters from the stream, close the stream
GetHTML = converter.ReadText
converter.Close
End Function
对象可以为您做到这一点,它也非常简单:
HTMLsearch()
我一直在这里使用MS Word并且正在调用?
正确地将西里尔字符写入页面。不过,对于我来说,它们仍然在MsgBox
中显示为{{1}},但现在这纯粹是一个显示问题,这是因为VBA创建的UI无法处理Unicode。

我的生产订单数据来自许多国家/地区。这是我能找到的唯一真正有效的vba函数。
Private Const CP_UTF8 = 65001
Private Declare Function MultiByteToWideChar Lib "kernel32" ( _
ByVal CodePage As Long, ByVal dwFlags As Long, _
ByVal lpMultiByteStr As Long, ByVal cchMultiByte As Long, _
ByVal lpWideCharStr As Long, ByVal cchWideChar As Long) As Long
Public Function sUTF8ToUni(bySrc() As Byte) As String
' Converts a UTF-8 byte array to a Unicode string
Dim lBytes As Long, lNC As Long, lRet As Long
lBytes = UBound(bySrc) - LBound(bySrc) + 1
lNC = lBytes
sUTF8ToUni = String$(lNC, Chr(0))
lRet = MultiByteToWideChar(CP_UTF8, 0, VarPtr(bySrc(LBound(bySrc))), lBytes, StrPtr(sUTF8ToUni), lNC)
sUTF8ToUni = Left$(sUTF8ToUni, lRet)
End Function
示例用法:
Dim sHTML As String
Dim bHTML() As Byte
bHTML = GetHTML("http://yoururlhere/myorderdata.php")
sHTML = sUTF8ToUni(bHTML)
sHTML = Mid(sHTML, 2) 'strip off Byte Order Mark: EF BB BF
