某些文案宽度计算错误问题

[enefry]

视乎是系统的接口有问题。在出现阿拉伯这种神奇文本的时候，宽度计算有问题

在 >>不知道:ج<< 这样一串文案中 1.使用：

[self boundingRectForGlyphRange:[self visibleGlyphRange]].size; 

计算出来的宽度是：124.4062158397378 （×）

2.使用

[_layoutManager usedRectForTextContainer:_textContainer].size 

计算出来的宽度是：53.183025966320074 （√）

在 tytextrender 中代码打印相关信息:

- (CGSize)textSizeWithRenderWidth:(CGFloat)renderWidth {
    if (!_textStorageOnRender) {
        return CGSizeZero;
    }
    CGSize size = _textContainer.size;
    _textContainer.size = CGSizeMake(renderWidth, MAXFLOAT);
    [self.textStorage enumerateAttributesInRange:NSMakeRange(0, self.textStorage.length) options:0 usingBlock:^(NSDictionary<NSAttributedStringKey,id> * _Nonnull attrs, NSRange range, BOOL * _Nonnull stop) {
        NSLog(@"textSizeWithRenderWidth:文本>>%@<<完 =>大小%@ ",[[self.textStorage attributedSubstringFromRange:range]string],NSStringFromCGRect([self boundingRectForGlyphRange:range]));
    }];
    CGSize textSize = [_layoutManager usedRectForTextContainer:_textContainer].size;// //[self boundingRectForGlyphRange:[self visibleGlyphRange]].size;
    _textContainer.size = size;
    return CGSizeMake(ceil(textSize.width), ceil(textSize.height));
}

(lldb) po self.textStorage
不知道{
    NSBackgroundColor = "UIExtendedGrayColorSpace 0 0";
    NSColor = "UIExtendedSRGBColorSpace 1 0 0 1";
    NSFont = "<UICTFont: 0x12741a470> font-family: \".PingFangTC-Regular\"; font-weight: normal; font-style: normal; font-size: 14.00pt";
    TYTextAttribute = "<TYTextAttribute: 0x283984fc0>";
    TYTextHighlightAttribute = "<TYTextHighlight: 0x282384a40>";
}:{
    NSFont = "<UICTFont: 0x125fc9e20> font-family: \"Helvetica\"; font-weight: normal; font-style: normal; font-size: 12.00pt";
}ج{
    NSFont = "<UICTFont: 0x1272123a0> font-family: \"Geeza Pro\"; font-weight: normal; font-style: normal; font-size: 12.00pt";
}
