Summary: This is needed so we can use generic columnWidthUTF8 in clang-format on win32 simultaneously with a separate system-dependent implementations of isPrint/columnWidth in TextDiagnostic.cpp to avoid attempts to print Unicode characters using narrow-character interfaces (which is not supported on Windows, and we'll have to figure out how to handle this).
