Question mark is often used for characters that have no code point in
the charset. So, what is the code point of the character that turns into
a question mark? Does that same code point output okay some of the time?
Of course, this explanation is a bit dubious if input is UTF-8, internal
encoding is UTF-8 and output is UTF-8.

Ah, could you be reading a partial multi-byte character and processing
it? E.g. taking an extreme example if you read 8 bytes, process them,
then repeat with the next 8 bytes, and they are an equal mix of
characters 1, 2 and 3 bytes long then there is a high probability you
will processing garbage.

What i'm doing now is reading the file in a bad sector with the function
file_get_contents() and sending it to the screen. It does not fail from the
file_get_contents() side when it does fail from the php.exe side.

moved to a different virtual server with a different executable version, same
hard drive phpinfo() now clearly states Multibyte Support enabled
no optimization engine here
lets wait untill the question marks start getting into databases

Hello everyone,
My name is Joel Sahleen and I am a PHP developer living in the Salt Lake
City, UT area. My background is in Chinese and Japanese, both of which I
studied at Stanford University as part of my graduate program in Asian
Languages. I have been programming in PHP for about 2.5 years now (read
career change) and recently received my ZCE certification.
I am currently interviewing with a large web analytics company located in
Utah who want me to help localize their products for the East Asian market.
Although I have the linguistic background and the necessary programming
skills, I have never implemented a localization project before and I was
hoping that people on the list could point me toward some good resources to
help get me started. I understand that the new intl implementation of ICU is
probably the best way to go for doing conversions, but how does this work
together with other technologies such as gettext? My potential employers
primary concerns are performance and manageability. Which strategies would
best satisfy those requirements?
Any help or suggestions would be greatly appreciated!!
Thanks.
Joel D. Sahleen
