一篇国外博文《Finding the Best Programmer's Font》中，作者指出一个理想的编码字体应具备以下要素：
Crisp clear characters. Extended characterset. Good use of whitespace. 'l', '1' and 'i' are easily distinguished '0', 'o' and 'O' are easily distinguished forward quotes from back quotes are easily distinguished -prefer mirrored appearance Clear punctuation characters, especially braces, parenthesis and brackets作为编码最常用的字体之一，Consolas字体非常受欢迎。但它的双下划线是连在一起的。
尽管如今的编码规范已基本摒弃了双下划线，不过这仍可视为Consolas的美中不足。
