Buildfarm member hamerkop has a niggle about this patch: c:\\build-farm-local\\buildroot\\head\\pgsql.build\\contrib\\fuzzystrmatch\\daitch_mokotoff.c : warning C4819: The file contains a character that cannot be represented in the current code page (932). Save the file in Unicode format to prevent data loss
It's complaining about the comment in static const char iso8859_1_to_ascii_upper[] = /* "`abcdefghijklmnopqrstuvwxyz{|}~ ¡¢£¤¥¦§¨©ª«¬ ®¯°±²³´µ¶·¸¹º»¼½¾¿ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõö÷øùúûüýþÿ" */ "`ABCDEFGHIJKLMNOPQRSTUVWXYZ{|}~ ! ?AAAAAAECEEEEIIIIDNOOOOO*OUUUUYDSAAAAAAECEEEEIIIIDNOOOOO/OUUUUYDY"; There are some other comments with non-ASCII characters elsewhere in the file, but I think it's mainly just the weird symbols here that might fail to translate to encodings that are not based on ISO 8859-1. I think we need to get rid of this warning: it's far from obvious that it's a non-issue, and because the compiler is not at all specific about where the issue is, people could waste a lot of time figuring that out. In fact, it might *not* be a non-issue, if it prevents the source tree as a whole from being processed by some tool or other. So I propose to replace those symbols with "... random symbols ..." or the like and see if the warning goes away. If not, we might have to resort to something more drastic like removing this comment altogether. We do have non-ASCII text in comments and test cases elsewhere in the tree, and have not had a lot of trouble with that, so I'm hoping the letters can stay because they are useful to compare to the constant. regards, tom lane
