Artemis .ast files fail to parse

[Tooko1005]

I've discovered an issue where, at least with one game, Yukiiro Sign, VNTextPatch fails to parse the .ast files, merely reporting 0 lines and characters. All of the scripts are encoded UTF-8, and I've confirmed they render correctly when opened in a text editor. I've attached the script files for reference.

How about Sakura no Uta after H2O -FOOTPRINTS IN THE SAND-?

Yukiiro sign is highly get localized by Shiravune since they have released Chinese translation for it
