ash: fix corruption of ${#var} if $var contains UTF-8 characters
As reported in bug 8506:
$ X=abcdÉfghÍjklmnÓpqrstÚvwcyz
$ echo ${#X}
abcd26
The result should be 26.
This regression was introduced by:
<d68d1fb> 2015-05-18 [Ron Yorston] ash: code shrink around varvalue
The length in characters was being used to discard the contents of
the variable instead of the length in bytes.
