Ohhhh… that's just… the way everything was in the early days of computing -- if there was a choice to be made, no matter how small, it would be done both ways by competing groups. Thank goodness that sort of thing never happens any more; our maturity and communications technologies have combined to make such dust-ups just a quant historic artifact to be wondered at.
Thanks ever so much Michael, for learning me something new today,
All the Best,

In "normal" communication, it's rarely a problem, because we usually have context to refer to. A special circle of hell is reserved for companies that generate license keys that have both characters, and are printed in a font wherein both characters are nearly identicalŠ :)
