Re^2: If two variables match

Side note on option 1. English may let you get away with uc'ing to do a comparison. Certain other languages do not. It's just a good I18N habit to get into to always use lower-case to compare. I've never really fully understood this advice from our I18N experts at work, but I take their word for it. Even if that makes me a bit of a cargo-culter. I'm not ashamed to admit it - I'm a unilingual person, so to keep from ticking off our Nordic customers, I'm more than happy to follow this advice. ;-)

Also, side note on option 2 - I think that option 1 is likely to be significantly faster. Benchmark to be sure.

If you want to give your language experts a counter example, in German, the "sharp-S" / "eszet" letter "ß", compounded of "s" and "z", has no uppercase equivalent and is always written as "SS" when uppercased. For example `straße` ("street") becomes `STRASSE`. If you want to match case-insensitively here, you either have to normalize all ß to "`ss`" before comparing or you can "normalize" by converting to upper case. But I admit that this is some corner case which is unlikely to affect non-Germans :-)	[reply]
