            Bug ID: 197775
           Summary: Impossible to achieve proper Greek capitalization
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

<h4>Without <code>lang</code> attribute:</h4>
<p style="text-transform: uppercase">ένα</p>

<h4>With <code>lang</code> attribute:</h4>
<p lang='el' style="text-transform: uppercase">ένα</p>

The two lines should be different. They are different in Chrome and Firefox, but not WebKit.

This is likely due to:

Ref<StringImpl> StringImpl::convertToUppercaseWithLocale(const AtomicString& localeIdentifier)
{
    // Use the more-optimized code path most of the time.
    // Assuming here that the only locale-specific lowercasing is the Turkish casing rules,
    // and that the only affected character is lowercase "i".
    if (!needsTurkishCasingRules(localeIdentifier) || find('i') == notFound)
        return convertToUppercaseWithoutLocale();
