This better matches the CRuby logic that calls the equivalent function and brings in BOM support.
Roughly ported from CRuby. See ruby@b249631

JRuby is still not green but it reduces the failure count by 5, exactly the number of tests that failed due to missing @nobu This is ready for review and merge. I will try to get the remaining tests green some day. |

Is this still needed?
It seems that we already use EncodingUtils#extractModeEncoding.

Fixed in upcoming push.

Can we move them to the bellow if (!options.isNil()) { ... } block?

Fixed in upcoming push, and vmodeVperm and oflags are now allocated once since they are never read by StringIO.

Just a nitpick: why len < 2?
| if (len < 2) break; | |
| if (toUnsignedInt(bytes[p + 1]) == 0xBB && len > 2) { | |
| if (len < 3) break; | |

The original logic was ported from the C code:
https://github.com/ruby/stringio/blob/master/ext/stringio/stringio.c#L229-L230
Are you sure this should change to len < 3?

I believe this is resolved in the other comment from @kou.
The code does use extractModeEncoding now.
* Only prepare carrier objects if we'll make the call * Cache the two carrier objects that are actually read (vmodeVperm is read inside extractModeEncoding so can't be a simple constant).

Thanks. |

Could we get a release? The updated ruby specs now test this method, so we fail those specs until we can update stringio. |

Done! |
