Harry Fuecks, who is a great guy, quotes Joel Spolsky about the apparent lack of international support for PHP.
This is so 2003. It ignores the fantastic work by hirokawa, moriyoshi, yohgaki and other japanese coders on the mbstring extension. PHP has worked well with multi-byte character sets since 4.3, especially when UTF-8 is used as the base for your work. The iconv extension is pretty cool also.
PS: Another good title for this piece is: When you meet Buddha on the road, shoot him, but I've already used it.
Update: Harry responds and says there is a lot more to be done for il8n (i always thought it was a silly name for internationalisation support).
