RFR(S): 8139996: CompileCommand prints quoted ascii strings

[Nils Eliasson]

Hi all,

This change makes method matchers (used by compile commands and compiler 
control) print symbols as utf8 instead of ascii. The print out of used 
commands will now look the same as the patterns the user has supplied.
