fix: crash when input line is invalid utf8

The input is passed to normalizer.nfd. Previously it was assumed that the input was valid utf8. If the input contained invalid bytes, zf would panic and exit. This is a temporary workaround. A future commit will remove zyglyph entirely and this will no longer be an issue. Closes #58
