[Bug]: [package] sed 4.8 - does not work with UTF-8 characters

[Balamoote]

Problem description

The termux 'sed' GNU sed v.4.8 does not see UTF-8 characters.
Note: the busybox sed v.4.0 (not GNU sed) works without problem

What steps will reproduce the bug?

$ echo ааабббггг | sed -E 's/ббб/жжж/g'
$ ааабббггг

That is no substitute happens.

What is the expected behavior?

$ echo ааабббггг | sed -E 's/ббб/жжж/g'
$ ааажжжггг <--- expected output

NOTE: the busybox sed work correctly:
$ echo ааабббггг | busybox sed -E 's/ббб/жжж/g'
$ ааажжжггг
