I guess it's a matter of choosing the right standard for the right purpose. For \uXXXX and \UXXXXXXXX the intention was to be able to represent a Unicode code point using its standard Unicode ordinal representation and since the standard uses hex for this, it's quite natural to use the same here. >> Take e.g. >> >>>>> s = "\u123456" >>>>> s >> 'ሴ56' >> >> With decimal notation, it's not clear where to end parsing >> the digit notation. > > How it is not clear if the digit amount is fixed? Not very clear what > did you mean. Unicode code points have ordinals from the range [0, 1114111], so it's not clear where to stop parsing the decimal representation and continue to interpret the literal as regular string, since I suppose you did not intend everyone to have to write \u0000010 just to get a newline code point to avoid the ambiguity. PS: I'm not even talking about the breakage such a change would cause.
