# This file contains characters that render as spaces (at least for me in vim)
# but are encoded as 160. Each is indicated with a "^" on the following line.
# 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.
