Components for Email, Zip Compression, Encryption, XML, S/MIME, and Character
Encoding Conversion
Character encoding conversion class. Convert text or HTML documents from one charset to another. All major character encodings are supported, including utf-8, ucs-2 (unicode) iso-8859-*, windows-*, shift-jis, iso-2022-jp/kr/cn, euc-jp/kr/cn, gb2312, big5, tis-620, and more.
 |
Properties | Description | ||
| FromCharset | Character encoding of source data,
such as "iso-8859-1", "utf-8", or "euc-kr".
|
|||
| LastError | XML error information for the last failed method call.
|
|||
| LastInputAsHex | The input data for the most recent character encoding conversion
in hexidecimal format. Useful for debugging.
|
|||
| LastInputAsQP | The input data for the most recent character encoding conversion
in quoted-printable format. Useful for debugging.
|
|||
| LastMethodFailed | True if the last method call failed.
|
|||
| LastOutputAsHex | The output data for the most recent character encoding conversion
in hexidecimal format. Useful for debugging.
|
|||
| LastOutputAsQP | The output data for the most recent character encoding conversion
in quoted-printable format. Useful for debugging.
|
|||
| SaveLast | If true, the component will save
the input and output data for the last conversion, which can then be retrieved
in quoted-printable format.
|
|||
| ToCharset | Character encoding of destination,
such as "iso-8859-1", "utf-8", or "euc-kr".
|
|||
| Version | The version of the component, such as "9.0.0"
|
|
Methods | Description | ||
| ConvertData | Converts text data from one charset to another. Returns the converted data. The text is converted according to the FromCharset and ToCharset properties.
|
|||
| ConvertFile | Convert a file from one character encoding to another.
The file is converted according to the FromEncoding and ToEncoding properties.
Returns true if the conversion is successful.
|
|||
| ConvertFromUnicode | Convert Unicode wide-character data to a multibyte character encoding
such as iso-8859-1, utf-8, shift-jis, big5, gb2312, tis-620, etc.
|
|||
| ConvertHtml | Converts HTML text to another charset. The "from" charset is determined by parsing out the charset information found in a META-tag, or if that is not present, it uses the FromCharset property. The HTML is converted to the charset specified by the ToCharset property. The META-tag is updated, or added if it previously did not exist. The converted HTML is returned. If the HTML could not be converted, a NULL is returned.
|
|||
| ConvertHtmlFile | Converts HTML text to another charset. The "from" charset is determined by parsing out the charset information found in a META-tag, or if that is not present, it uses the FromCharset property. The HTML is converted to the charset specified by the ToCharset property. The META-tag is updated, or added if it previously did not exist. Returns true if successful, otherwise false.
|
|||
| ConvertToUnicode | Convert multibyte character data to a Unicode wide character string.
Multibyte character encodings include iso-8859-*, euc-*, iso-2022-*, windows-125*, utf-8,
and anything else except for ucs-2 or Unicode.
|
|||
| DetectCharset | Tries to detect the charset by examining the character data. This method is more accurate when more data is available to examine, but is never 100% accurate.
|
|||
| DownloadHtml | A convenient method to download the HTML from a URL. It does not download all external referenced parts of the Web page -- it only downloads the HTML text of a page. A NULL is returned if the Web page could not be downloaded.
