This is not a simple problem. The short-term fix is to allow
all chars with codes >= 32. However, in UTF-8 non-ASCII chars
(German umlauts etc) are actually multi-byte sequences,
and they cannot be checked for validity by looking at single
character's code.

for now, ENABLE_FEATURE_VI_8BIT in vi allows any chars with codes >= 32
(except for 0x9b which is a control char for VT-100 terminals (STUPID!!!)).
Umlauts should work in vi, if they are single chars, not UTF-8 sequences.
