To overrite the encoding when *writing*, you should the ENCODING layer 
creation option :

ogr2ogr out.shp indatasource -lco ENCODING=UTF-8

Note: in that case, the encoding of the input datasource must be already 
encoded in UTF-8, which is the pivot encoding for OGR. The effect of  -lco 
ENCODING=UTF-8 will be essentially to write a .cpg file with UTF-8 as its 
content. Apart from using a value of the form LDID/a_numeric_value where 
a_numeric_value is a value in the first column of table 9 of 
http://www.autopark.ru/ASBProgrammerGuide/DBFSTRUC.HTM (from 1 to 204), it is 
not entirely clear which other values are valid for the ENCODING parameter to 
have interoperability with other systems.

The SHAPE_ENCODING configuration option/environment variable is to be used when 
you want to override the encoding indicated in the .dbf/.cpg file when reading 
a shapefile. It can be set to any valid value recognized by the iconv library, 
whose list you can get with iconv -l on a system with iconv binaries 
installed. In that case, OGR will recode from SHAPE_ENCODING to UTF-8. If you 
want no recoding to happen, you can set SHAPE_ENCODING="".
