42. Translating strings
gettext()
Depends on setlocale() , which is not thread-safe
QT Linguist
XML based format used in QT
PHP Arrays
PHP Constants
PHP implementation for gettext files
Should not depend on setlocale()
Will be slower

43. Plural forms
Most libraries somehow support plural forms
Support singular
Support simple plural forms
Support different plural forms depending on number
Support multiple words with plural forms in one sentence

47. Finding strings
Locating untranslated strings
Plain strings are “trivial” to find
Parameterized strings are possible to find
Error messages created in applications are impossible to find
Handling untranslated strings
Use proper message as identifier (not MY FOO ERRORMSG1 )
Add “context”
Append strings to storage as “untranslated”

Make it easy for them
There are various websites which make collaboration easy
Commonly support QT Linguist and gettext
There is a GUI for QT Linguist translations
