Try this function:

fun! RevChars()
	let line=getline('.')
	let newline=''
	let hi=strlen(line)-1
	while hi >= 0
		let newline = newline . line[hi]
		let hi=hi=1
	endwhile
	call setline('.', newline)
endfun

Now try it on the line:
	abcdefg

you will get as expected:
	gfedcba


Now try it on the line containing the utf8 characters (hex Unicode
values given for transport reasons):
	05ea 05e8 05d2 05d9 05d0

you will get:
	0090 05d9 05d2 05e8 0fea 00d7
