NGUI UILabel change the size of part of text by bbcode tag?

[probmak]

Is this possible?
I can change part of text UILable using color and other tags. For example, "[FF0000FF]red text[-], default color text". This will change the color of several letters.
Do, Can I change the size of several letters in one UILabel using tags?

You can use [ sub ] and [ sup ] tags to shrink your text, but there's nothing to enlarge it, no.
