Look at Python/ast.c, which has functions parsestr() and decode_unicode().
The latter calls PyUnicode_DecodeRawUnicodeEscape() which I think is the

Four shall be the number of spaces thou shalt indent, and the number of thy
indenting shall be four. Eight shalt thou not indent, nor either indent thou
two, excepting that thou then proceed to four. Tabs are right out.
