// REQUIRES: asserts
Nicer display of unprintable source, and fix caret display for non-ascii text Unprintable source in diagnostics is transformed to a printable form and then displayed with reversed colors if possible. Unprintable characters are displayed as <U+NNNN> while bytes that do not represent valid characters are shown as <XX>. Column adjustments to diagnostic carets, highlighted ranges, and fixups are made both for characters escaped as above and for characters which are printable but take up more than a single column. llvm-svn: 154980

When a bad UTF-8 encoding or bogus escape sequence is encountered in a string literal, produce a diagnostic pointing at the erroneous character range, not at the start of the literal. llvm-svn: 163459
