[IronPython] UTF-8 script every 1024 bytes are broken

[KATO Kanryu]

Hi,

When the IronPython parses UTF-8 scripts, it occars every 1024 bytes are broken.
Because UTF-8 charmap has multibyte chars, but parser read only 1024
byte at once.

Mr. Koichi Yamamoto had written a patch for the problem.

I'm glad to commit official repository.

Comments?
