Language codes are typically loaded from resource files. These are UTF-8 encoded text files. They are systematically named following the pattern:

org/apache/commons/codec/language/bm/${NameType.getName() languages.txt

The format of these resources is the following:

• Language: a single string containing no whitespace
• End-of-line comments: Any occurrence of '//' will cause all text following on that line to be discarded as a comment.
• Multi-line comments: Any line starting with '/*' will start multi-line commenting mode. This will skip all content until a line ending in '*' and '/' is found.
• Blank lines: All blank lines will be skipped.
