Indicating direction of an object using a basic string

I am trying to indicate the direction (left or right) of an object relative to a fixed point, which is itself located relative to a standard center, using simple text.

This direction information is important, as it determines which of two otherwise identical locations is indicated. The same position may be presented graphically, but not necessarily at the same time as its written form.

Basically, I am trying to represent a horizontal point in the following form:

3.0 steps left of the right 45 yl

(yl being Yard Line, and the 50 yl being Center)

Or...

3.0 steps left of the ➢ 45
                       ?
3.0 steps left of the 45 ➢

I think I have a good general format, but I'm concerned that it might not be easily recognizable in a quick glance, what with the "left of the right" going on there...

I have come up with a few options to remedy this situation:

  1. Just use "Left" and "Right"
  2. Some arrow character
  3. Subscripts

The first option would be simple enough, but I'd rather not use that if I can avoid it, for reasons listed above.

I have searched Unicode docs and those of various fonts in search of a character to use for this purpose. I am particularly fond of the 3D TOP-LIGHTED RIGHTWARDS ARROWHEAD (➢), but I have yet to find a viable leftwards equivalent. It's a simple matter to create and insert a rotated version of the character myself, but this leads to a host of other issues, not the least of which is that of performance. I'd rather not have to pass around a complex attributed string, and re-insert my rotated glyph image every time I pass move the string elsewhere. And where should I insert the arrow? To the right or left of the line number?

The third option is one I have seen used in a few places. Side 1 would be left of the 50, and side 2 is right, from the stands' perspective. This number would be subscripted after the line number.

Any advice on this point would be appreciated. How would I best convey this information without confusing my users?
