Trainz/references/Filename character restrictions

1 1 Filename syntaxes (or name formation) in Trainz assets are heavily restricted for compatibility reasons. As filenames are not displayed to end-users, there is no need for localization support (File and directory paths) or other format class characters. Specifically, filenames within Trainz must obey the following rules: Filenames must not begin with a space (' '), a period ('.'), or a tilde ('~'). Filenames must be at least one character long. Filenames must not end with a space (' '). Filenames should be kept to a reasonable length. No fixed length is currently enforced, however if compatibility issues arise at a later date N3V Games may add length limits. Smart quotes, accents, umlauts and other non-ASCII characters are disallowed. Filenames must consist of the following ASCII characters only: Filenames must consist of the following ASCII characters only: 'a' through 'z' lowercaseletters 'A' through 'Z' uppercaseletters '0' through '9' numbers hyphen  ' - '  ampersand  ' & '  comma  ' , '  plus  ' + '  apostrophe  '  '  '  period  ' . '  underscore  ' _ '  dollar  ' $ '  space  '   '  open parenthesis  ' ( '  closed parenthesis  ' ) '  tilde  ' ~ '  1 1 http://online.ts2009.com/mediaWiki/index.php/Filename_character_restrictions a 1 character restrictions
