From: Jarkko Hietaniemi Date: Wed, 25 Oct 2000 20:00:48 +0000 (+0000) Subject: Continue the internal UTF-8 API tweaking. X-Git-Tag: accepted/trunk/20130322.191538~33851 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dcad28805702d580064bc39a267d63c58bbb3b3f;p=platform%2Fupstream%2Fperl.git Continue the internal UTF-8 API tweaking. Rename utf8_to_uv_chk() back to utf8_to_uv() because it's used much more than the simpler API, now called utf8_to_uv_simple(). Still not quite happy with API, too much partial duplication of functionality. p4raw-id: //depot/perl@7439 --- diff --git a/doop.c b/doop.c index 3cd8f07..fa927c2 100644 --- a/doop.c +++ b/doop.c @@ -77,7 +77,7 @@ S_do_trans_simple(pTHX_ SV *sv) ulen = 1;
