2176c5e510
This patch fixes the display of characters appearing in LHS or RHS of == expression in notes to static assertion failure. This applies C-style escape if the printed character is a special character. This also adds a numerical value displayed next to the character representation. This also tries to print multi-byte characters if the user-provided expression is multi-byte char type.
