There is a crash when parsing an RTF file with invalid encoding, i.e. multiple closing } without opening ones. The crash occurs on this line and happens when l==0:

A simple fix is to check if l > 0 and then continue parsing of the invalid RTF encoded file:

if l := len(stack); l > 0 {
	entry := stack[l-1]
	stack = stack[:l-1]
	ucskip = entry.NumberOfCharactersToSkip
	ignorable = entry.Ignorable
}

Hi! This function was actually super useful. Could you please add a LICENSE (e.g. MIT/BSD/MPL/Apache/...??)
