ABCL and unicode support
Looking at some of the tests for ASDF, I see that ABCL is flagged as not having Unicode support. See https://gitlab.common-lisp.net/asdf/asdf/-/blob/master/uiop/common-lisp.lisp#L32-40
TBQH, I'm not sure what the feature
asdf-unicode is supposed to signal. The only use of this feature that I can find is here: https://gitlab.common-lisp.net/asdf/asdf/-/blob/master/uiop/stream.lisp#L94-103 In this context the variable
*utf-8-external-format* is set to
:utf-8 when the feature is present or, when it's not (as on ABCL), it's set to
@mevenson Will you please have a look at this and let me know if you think I should push that feature for ABCL? And if so, if there's a version at which you consider such support to be added?
