That's not an error: 4 is less than 33. Version numbers are tuples
compared component-by-component, not decimal, so 2.4 < 2.33 < 2.100 (and
2.4 is not the same as 2.40 or 2.40000). glibc 2.4 is a version from
about 15 years ago.

In packages that have more than two components in their version numbers,
like GTK 3.24.33, it's more obvious that it can't be a decimal number,
but the correct version-comparison for libc6 works the same as it does
for GTK.

The maintainers of gucharmap are likely to need more information to
work out why it is drawing in white-on-white for you; it's working fine
for me (black symbols on a white background). The output of

    reportbug --template gucharmap

would be a good start.
