Yet the grammar defines nonascii as anything beyond 177 which is U+00B1 which does not really make sense to me. Thinking about it some more explicitly excluding 127-160 does not really seem needed either to me and maybe they should become part of nonascii (would also make the name somewhat more logical).

I take it you're referring to the line

	nonascii	[^\0-\177]

The \177 there is an OCTAL escape, so that means 127 decimal / 0x7f hex, which is correct for the ASCII range.
