    Better unicode character display-width calculation (in columns)

    Tested with Windows Terminal Version: 1.18.10301.0 and all codepoints between 0x100 and 0x1FFFF, this change reduces the width mismatches from > 8000 to
    349. The "Zero width" mismatches are probably the most important/glaring and will need to be addressed next (since some terminals don't move the cursor
    for zero width chars, and some do).

    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.
