NAME ^

Win32::MultiLanguage - Interface to IMultiLanguage I18N routines

SYNOPSIS ^

  use Win32::MultiLanguage;
  # @@

DESCRIPTION ^

Win32::MultiLanguage is an experimental wrapper module for the Windows IMultiLanguage interfaces that comes with Internet Explorer version 4 and later. Mlang.dll implements routines for dealing with character encodings, code pages, and locales.

ROUTINES ^

DetectInputCodepage($octets [, $flags [, $codepage]])

Detects the code page of the given string $octets. An optional $flags parameter may be specified, a combination of MLDETECTCP constants as defined above, if not specified MLDETECTCP_NONE will be used as default. An optional $codepage can also be specified, if this value is set to zero, this API returns all possible encodings. Otherwise, it lists only those encodings related to this parameter. The default is zero.

It will return a reference to an array of hash references of which each represents a DetectEncodingInfo strucure with the following keys

  'LangID'     => ..., # primary language identifier
  'CodePage'   => ..., # detected Win32-defined code page
  'DocPercent' => ..., # Percentage in the detected language
  'Confidence' => ..., # degree to which the detected data is correct
GetCodePageInfo($codepage, $langid = GetUserDefaultLangID())

Returns a hash reference describing $codepage if known with strings in $langid, for example:

  'GDICharset'       => 1,
  'HeaderCharset'    => 'utf-8',
  'Flags'            => 805701387,
  'WebCharset'       => 'utf-8',
  'CodePage'         => 65001,
  'ProportionalFont' => 'Arial',
  'BodyCharset'      => 'utf-8',
  'Description'      => 'Unicode (UTF-8)',
  'FixedWidthFont'   => 'Courier New',
  'FamilyCodePage'   => 1200
GetCodePageDescription($codepage, $locale = GetUserDefaultLCID())

Returns a human-readable description of $codepage in $locale, for example,

  Western European (Windows)

for Windows-1252 in 1033 (English (United States)).

GetRfc1766FromLcid($lcid = GetUserDefaultLCID())

Get the RFC 1766 identifier that corresponds to $lcid.

DetectOutboundCodePage($utf8 [, $flags [, \@cp ]])

...

GetCharsetInfo($charset)

If the $charset string is known, returns a hash reference like this:

  InternetEncoding => 65001,
  CodePage         => 1200,
  Charset          => 'utf-8'

Returns nothing if the encoding is unknown.

IsConvertible($CodePageIn, $CodePageOut)

Checks if transcoding from $CodePageIn to $CodePageOut can be performed.

GetRfc1766Info($lcid = GetUserDefaultLCID(), $langid = GetUserDefaultLangID())

Information about the $lcid in $langid, for example

  'Lcid'       => 1033,
  'LocaleName' => 'English (United States)',
  'Rfc1766'    => 'en-us'
GetLcidFromRfc1766($rfc1766)

Get the locale identifier that corresponds to the $rfc1766 identifier. Also returns a second value indicating whether "The returned LCID matches the primary language of the RFC1766-conforming name only" [@@ in list context];

GetFamilyCodePage($codepage)

The family code page that corresponds to $codepage.

GetNumberOfCodePageInfo()

The number of available code pages.

GetNumberOfScripts()

The number of available scripts.

EnumCodePages($flags = 0, $langid = GetUserDefaultLangID())

Returns a list of code page information hash references matching $flags with strings in $langid.

EnumScripts($flags = 0, $langid = GetUserDefaultLangID())

Returns a list of script information hash references matching $flags with strings in $langid.

EnumRfc1766($langid = GetUserDefaultLangID())

Returns a list of RFC 1766 information hash references with strings in $langid.

Transcode($CodePageIn, $CodePageOut, $String, $Flags)

Uses the IMLangConvertCharset::DoConversion method to convert between the two code pages. Sets the UTF-8 flag if CodePageOut == CP_UTF8 and croaks if the conversion is not supported. Returns nothing if it fails. It seems the empty string cannot be transcoded by DoConversion, so do not pass the empty string to it, unless you handle the failure in some way.

CONSTANTS ^

These are currently not exported/exportable.

MLDETECTCP

MLDETECTCP_NONE

Default setting will be used.

MLDETECTCP_7BIT

Input stream consists of 7-bit data.

MLDETECTCP_8BIT

Input stream consists of 8-bit data.

MLDETECTCP_DBCS

Input stream consists of double-byte data.

MLDETECTCP_HTML

Input stream is an HTML page.

MIMECONTF

MIMECONTF_MAILNEWS

Code page is meant to display on mail and news clients.

MIMECONTF_BROWSER

Code page is meant to display on browser clients.

MIMECONTF_MINIMAL

Code page is meant to display in minimal view. This value is generally not used.

MIMECONTF_IMPORT

Value that indicates that all of the import code pages should be enumerated.

MIMECONTF_SAVABLE_MAILNEWS

Code page includes encodings for mail and news clients to save a document in.

MIMECONTF_SAVABLE_BROWSER

Code page includes encodings for browser clients to save a document in.

MIMECONTF_EXPORT

Value that indicates that all of the export code pages should be enumerated.

MIMECONTF_PRIVCONVERTER

Value that indicates the encoding requires (or has) a private conversion engine. A client of IEnumCodePage doesn't use this value.

MIMECONTF_VALID

Value that indicates the corresponding encoding is supported on the system.

MIMECONTF_VALID_NLS

Value that indicates that only the language support file should be validated. Normally, both the language support file and the supporting font are checked.

MIMECONTF_MIME_IE4

Value that indicates the Microsoft® Internet Explorer 4.0 MIME data from MLang's internal data should be used.

MIMECONTF_MIME_LATEST

Value that indicates that the latest MIME data from MLang's internal data should be used.

MIMECONTF_MIME_REGISTRY

Value that indicates that the MIME data stored in the registry should be used.

MLDETECTF

MLDETECTF_MAILNEWS

Not currently supported.

MLDETECTF_BROWSER

Not currently supported.

MLDETECTF_VALID

Detection result must be valid for conversion and text rendering.

MLDETECTF_VALID_NLS

Detection result must be valid for conversion.

MLDETECTF_PRESERVE_ORDER

Preserve preferred code page order. This is meaningful only if you have set the @@puiPreferredCodePages parameter in DetectOutboundCodePage.

MLDETECTF_PREFERRED_ONLY

Only return one of the preferred code pages as the detection result. This is meaningful only if you have set the @@puiPreferredCodePages parameter in DetectOutboundCodePage.

MLDETECTF_FILTER_SPECIALCHAR

Filter out graphical symbols and punctuation.
