# This file contains characters that render as spaces (at least for me in vim)

# FileCheck used to call functions like isalnum on each without casting to
|
|
|
# unsigned char first, so it sign-extended beyond what unsigned char or EOF can
|
|
|
# represent. C says that has undefined behavior, and it has caused stack dumps
|
|
|
# under Windows.
