Log Message:
xpdev: approximate the remaining dashes as an ASCII hyphen for CP437

unicode_to_cp437() knew about EM DASH but not the four narrower dashes,
so U+2010 HYPHEN, U+2011 NON-BREAKING HYPHEN, U+2012 FIGURE DASH and
U+2013 EN DASH had no CP437 equivalent and came out as the unsupported character. CP437 has an exact glyph for none of them but a perfectly good approximation in the ASCII hyphen, which is already what
utf8_normalize_str() folds all four into.

This only shows up on the paths that convert without normalizing first;
where both run, normalization gets there first and the result is the same either way.
