Two things. First of all, the only non-ASCII characters I can find in the file are the three bytes of the UTF-8 BOM.
Secondly, all valid UTF-8-encoded Unicode characters are allowed in all LDraw files (including official library files). The current file format spec does forbid the BOM, but it explicitly states that all LDraw files must be UTF-8. The official library restrictions spec makes no mention of ASCII or UTF-8. So, since LDraw files are defined to be UTF-8, and the restrictions document doesn't require them to be pure ASCII, they are fully UTF-8.
