How could I produce characters which are outlined when the character itself is in some color. A picture to illustrate what I'm after:
The problems with the above are that:
- the outline is of no consistent width around the letter.
- the way I've done it (using tikz with a upscaled black node below the colored one), there is no easy way to control the width of the outline.
Do you know of a way to accomplish this with TeX? I am using plain-format with XeTeX, but I'm interested in all ways to accomplish this.
