[llvm-bugs] [Bug 37044] New: Unicode string literals

2018-04-07 Thread via llvm-bugs 
https://bugs.llvm.org/show_bug.cgi?id=37044

Bug ID: 37044
   Summary: Unicode string literals
   Product: clang
   Version: unspecified
  Hardware: Macintosh
OS: MacOS X
Status: NEW
  Severity: enhancement
  Priority: P
 Component: Frontend
  Assignee: unassignedclangb...@nondot.org
  Reporter: bumblebritche...@gmail.com
CC: llvm-bugs@lists.llvm.org

`\x` Does not work with Unicode characters outside of the BMP for example
U+1F984, and `\u` and `\U` (for UTF-16 and UTF-32) will not work with Unicode
characters in the ASCII range (for example, 0x20, the space).

I'm not entirely sure what to do here, I ran into this problem because I'm
writing a script to parse the Unicode Character Database to create some tables
in C for my library, StringIO.

Example code:

uint_least32_t Space32_1[] = U"\x20";
uint_least32_t Space32_2[] = U"\U20";
uint_least32_t Unicorn32_1[]   = U"\x1F984";
uint_least32_t Unicorn32_2[]   = U"\U1F984";
