I added some code in juce\_mac\_Fonts.mm to handle the reading direction from an AttributedString.

Would it&nbsp;be possible to put this&nbsp;into the code base?&nbsp;&nbsp;

In&nbsp;&nbsp;static CFAttributedStringRef createCFAttributedString (const AttributedString& text)&nbsp;the following was added.

&nbsp;

```
CTWritingDirection ctWritingDirection = kCTWritingDirectionNatural;

        switch (text.getReadingDirection()){

            case AttributedString::ReadingDirection::natural: break;

            case AttributedString::ReadingDirection::rightToLeft: ctWritingDirection = kCTWritingDirectionRightToLeft; break;

            case AttributedString::ReadingDirection::leftToRight: ctWritingDirection = kCTWritingDirectionLeftToRight; break;

        }

        CTParagraphStyleSetting settings[] =

        {

            { kCTParagraphStyleSpecifierAlignment, sizeof (CTTextAlignment), &ctTextAlignment },

            { kCTParagraphStyleSpecifierLineBreakMode, sizeof (CTLineBreakMode), &ctLineBreakMode },

            { kCTParagraphStyleSpecifierBaseWritingDirection, sizeof (CTWritingDirection), &ctWritingDirection},

            

           #if defined (MAC_OS_X_VERSION_10_7) && MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_7

            { kCTParagraphStyleSpecifierLineSpacingAdjustment, sizeof (CGFloat), &ctLineSpacing }

           #else

            { kCTParagraphStyleSpecifierLineSpacing, sizeof (CGFloat), &ctLineSpacing }

           #endif

        };
```

Thanks,

Darren

Thanks, sounds like a sensible addition, I'll take a look at that today!

Hello,

In juce\_max\_Fonts.mm, could this be changed to:

```
static CTWritingDirection getWritingDirection (const AttributedString& text)
    {
        switch (text.getReadingDirection())
        {
            case AttributedString::rightToLeft: return kCTWritingDirectionRightToLeft;
            case AttributedString::leftToRight: return kCTWritingDirectionLeftToRight;
            default: return kCTWritingDirectionNatural;
        }
    }
```

Removing&nbsp; "::ReadingDirection"&nbsp; ?

This is only thing that prevents building on Mac with less than C++11 (and consistent with the other use of enums).

Best,

Martin

Sure, will do, thanks Martin!
