Help with text effect in Dialog, please

[Osakawa]

I saw somewhere but forgot.
What can I do if I want to show a specific string with the blue color in Dialog?
Do you support RGB(X,y,z) as the color of a string?
How about bold text?
What if I want to make the string larger than the normal text? If I can't, can you please add this feature?
Or can you offer an option to set the UI text large, normal, or small?

Check the Guide under "Special Character"; there are a bunch of options for formatting text. :)
