highlight: fix more tracebacks by forcing util._encoding to hgweb.encoding

This is needed in case util._encoding and hgweb.encoding conflict.
Extreme example:
HGENCODING=UTF-8
[web]
encoding = ascii

Note:
display of files whose encoding differs from HGENCODING or hgweb.encoding
behaves not exactly the same way as with highlight turned off as replacement
chars are either converted or replaced.
