# Script to check that ICU source files contain only valid UTF-8 encoded text,
|
|
# and that all files except '.txt' files do not contain a Byte Order Mark (BOM).
|

#
|
|
# THIS SCRIPT DOES NOT WORK ON WINDOWS
|
|
# It only works correctly on platforms where the native line ending is a plain \n
|
|

# usage:
|
|
# icu-file-utf8-check.py [options]
|
|

# options:
|

# -h | --help Print a usage line and exit.

# The tool operates recursively on the directory from which it is run.
|
|
# Only files from the ICU github repository are checked.
|
|
# No changes are made to the repository; only the working copy will be altered.
|
|
# The script checks all source files and returns a non-zero exit code if any of
|
|
# the checked files contain a non-UTF-8 character.
