// Test case for the text diagnostics source column conversion crash.

// This test case tries to check the error diagnostic message printer, which is
// responsible to create the code snippet shorter than the message-length (in
// number of columns.)
//
// The error diagnostic message printer should be able to handle the non-ascii
// characters without any segmentation fault or assertion failure.  If your
// changes to clang frontend crashes this case, it is likely that you are mixing
// column index with byte index which are two totally different concepts.

// NOTE: This file is encoded in UTF-8 and intentionally contains some
// non-ASCII characters.
