please add this test pattern

C:\
└─d2
　│ bokura-config.d2
　│
　└─あ     <---( cp932 : windows japanese edition)
　　　 a.d2 <---( UTF-8/UTF-16 : d2 source file )

[bo-ku-ra]

d2 v0.6.7: success: successfully compiled

...@../bokura-config

d2 v0.6.7: unexpected text after import

...@file:///C:/d2/bokura-config

[bo-ku-ra]

v0.6.8 not yet?

[alixander]

@bo-ku-ra can you try

...@"C:/d2/bokura-config.d2"

[bo-ku-ra]

i've confirmed that it's fine on the windows japanese edition.
