This is all implemented in cross platform code, why does Blackberry have its own copy?

Hi Alexey, they are wrappers for the cross platform code. We have a layer between the WebKit and Browser App, these wrapper APIs are exposed to this layer, we are not going to expose or include the cross platform code to that layer directly.

OK

Informal review.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:28
> +#include "Vector.h"

#include <wtf/Vector.h> instead of #include "Vector.h".

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:36
> +namespace BlackBerry {
> +namespace WebKit {

I would keep only one empty line here.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:47
> +    TextEncoding te(encoding);

I would use textEncoding instead of te.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:57
> +    WTF::String enc(encoding);

WTF:: is not needed, should be removed. And I would change enc to encodingName.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:68
> +
> +

I would remove an extra empty line.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:71
> +    TextEncoding teSource(sourceEncoding);

I would change teSource to textEncodingSource.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:75
> +    TextEncoding teTarget(targetEncoding);

I would name the variable textEncodingTarget.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:82
> +    WTF::String ucs2 = codecSource.decode(sourceStart, sourceLength, true, true, sawError);

Remove WTF::.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:89
> +    WTF::CString encoded = codecTarget.encode(ucs2.characters(), ucs2.length(), WebCore::EntitiesForUnencodables);

Ditto.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:108
> +    WTF::Vector<char> vect;

Remove WTF::. I would rename vect to something like result.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:119
> +    WTF::Vector<char> vect;

Ditto.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:132

Remove WTF::.

I would remove this empty line.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:135

Remove WTF::.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:143
> +    WTF::String urlString(url.data(), url.length());

Remove WTF::.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:144

I would remove this empty line.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:146

Remove WTF::.

> +    WTF::String mimeString(mime.data(), mime.length());
> +
> +    WTF::String ext = WebCore::MIMETypeRegistry::getPreferredExtensionForMIMEType(mimeString);

Remove WTF::. I would change ext to extension.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:160
> +    WTF::CString utf8 = ext.utf8();

Remove WTF::.

> Source/WebKit/blackberry/Api/WebString.cpp:26

Could this line be removed?

> Source/WebKit/blackberry/Api/WebString.cpp:31
> +WebString::WebString(const char* latin1)
> +: m_impl(static_cast<WebStringImpl*>(WTF::StringImpl::create(latin1).releaseRef()))

You should add 4 spaces before the colon.

> Source/WebKit/blackberry/Api/WebString.cpp:36
> +: m_impl(static_cast<WebStringImpl*>(WTF::StringImpl::create(latin1, length).releaseRef()))

Ditto.

> Source/WebKit/blackberry/Api/WebString.cpp:41
> +: m_impl(static_cast<WebStringImpl*>(WTF::StringImpl::create(utf16, length).releaseRef()))

Ditto.

> Source/WebKit/blackberry/Api/WebString.cpp:59

Ditto.

Remove WTF::.

Ditto.

I would remove extra empty lines.

Ditto.

Looks good, r=me! Please fix these before landing, or upload another patch that I could cq+.

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:23
> +#include "CString.h"

<wtf/text/CString.h>

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:53
> +    String lowercasedEncoding = String(encoding).lower();
> +    if (lowercasedEncoding.startsWith("iso-8859")

We might want to add a comment here, that this is slow and could easily be optimized, by directly inspecting encoding[i].

> Source/WebKit/blackberry/Api/WebString.cpp:26
> +using WTF::String;

WTFString.h already declares that, this is unncessary here, no?

> Source/WebKit/blackberry/Api/WebString.cpp:109
> +    return WTF::equal(m_impl, utf8);

doesn't WTF already do "using WTF::equal" in their public headers?

> Source/WebKit/blackberry/Api/WebString.cpp:114
> +    return WTF::equalIgnoringCase(m_impl, utf8);

Ditto.

Keep WTF for equal() and equalIgnoringCase(), because the compiler was always trying to use  
WebString.equal() and WebString.equalIgnoringCase() instead of the WTF functions as the cadidates which caused compiling error when we removed WTF.

Some minor comments.

Wouldn't check-webkit-style complain about sorting problem? Sorting is case sensitive?

> Source/WebKit/blackberry/Api/WebKitTextCodec.cpp:32
> +using namespace WTF;

Is this needed?

If I remember correctly the ASCII of 'V' should be less than 't' and I don't see any complains.

String, CString and Vector are using it, however, the header files may already declare it.  I can try to remove.

Remove using namespace WTF in WebKitTextCodex.cpp as the WTFString and Vector header files already declares it for String, CString and Vector.
