4 years ago These 3-byte characters require variable-length output buffer which is slow.
Even if we pre-allocate a large-enough buffer these characters make reusing buffer sections hard, sections such as remaining time estimation and step counter will need to be pushed back.
I suggest falling back to plain # instead of UTF-8 bar fractions, including full bars: █
in short, use these
to characterize small fractions of progress.
We can achieve this with the ICU library, or with libraries like
<locale>and<codecvt>.The code points we're looking for is
