logo_width measured the logo with awk's `length`, which counts bytes unless the
locale is UTF-8. The logo is drawn in box-drawing glyphs, three bytes each, so
the answer was 197 columns rather than 81 anywhere LANG went unset — a console
booting before locale.conf applies, a shell that never inherited one.
A width wider than the terminal makes left_padding clamp its pad to zero, so the
logo sat flush left while the title, bar, and tip centered against a phantom
197-wide box and drifted right of it. The 81 this function already falls back to
when logo.txt is missing is the character count, so the intent was never in
question, only the measurement.
Count bytes deliberately under LC_ALL=C and drop the UTF-8 continuation bytes
before measuring. That is the same answer in every locale rather than the right
one only in those that have a charset.
