During features download, feature names are transformed into filenames. Below are the rules we use for transformation

FILENAME = FEATURE_NAME.replaceAll("[^a-zA-Z0-9]", " ").replaceAll("\s+", "-").trim().toLowerCase();

• Replace all non alphanumeric characters with single space [^a-zA-Z0-9] → “ “

• Replace multiple spaces with dash \s+ → “-“

• Trim

• Transform to lowercase

Example:

Feature name: Feature name transformation !#$%&'*+-/=?^_`{|}~

Transformed: feature-name-transformation
