For a text reader:

1. switch to a locale known to be different than English regarding
numerical rules, like French where "," and "." have opposite meaning.
2. read the file (assuming the file to read is encoded in C|POSIX locales)

For a text writer:
1. switch to a non English locale
2. write a file
3. switch to an English locale
4. read the file
