Make It Work In Turkey
Jeff Atwood advises globally-aware developers to make sure their applications work well for Turkish users. Because Turkish date and number formats differ significantly from American and British (and because Unicode support is a must), he says localizing to “tr” is a good test of your overall localization strategy.
There is also the infamous lowercase i problem.
Right-to-left languages such as Arabic and Hebrew seem to pose a much bigger challenge. Besides, Hebrew localization involves date conversion to/from a different calendar, as do other locales.
As many of the comments to Atwood’s article point out, there is a staggering amount of diversity in terms of sorting, stemming, and formatting various values. Relatively speaking, Turkish localization should be a snap.
