Not sure why using > WTF::String is helpful. This was my own personal preference, I much prefer dealing C++ types, than C or ObjC types. We are getting one of the version as a const char* and there other as a NSString*, both can silently be converted to String type, so this was convenient too. 1650390 5 398808 cdumez 2020-05-07 15:50:51 -0700 Created attachment 398808 Patch 1650391 6 cdumez 2020-05-07 15:51:13 -0700 (In reply to Chris Dumez from comment #5) > Created attachment 398808 [details] > Patch Fixes iOS build. 1650417 7 ews-feeder 2020-05-07 16:54:59 -0700 Committed r261360: <https://trac.webkit.org/changeset/261360> All reviewed patches have been landed.

The old code treated this as UTF-8. The new code treats it as Latin-1. But I suspect really this is all guaranteed to be ASCII so this change in behavior is not important. 398806 2020-05-07 15:37:11 -0700 2020-05-07 15:50:50 -0700 Patch bug-211600-20200507153710.patch
