designing the functional interface
Designing the functional interface
  • Plan for i18n when you create your specifications
  • Consider the nature of the data your application is processing
  • How will the majority of customers access the application?
  • Will users be working with one language at a time or with multiple languages?
some concepts and limitations
Some concepts and limitations
  • Each HTML page is limited to a single charset
  • The CGI script has no knowledge of the client
  • Provide customers ways to access the interface by language
  • Create a single home page displaying a choice of languages on it
  • Allow for customization of the initial access point
choosing the cgi language
Choosing the CGI language
  • Any programming language is internationalizable
  • The classic CGI script has no persistence in server memory
  • There are server utilities that provide an API for CGI scripts
  • Java servlets are persistent as well, but they require Web servers with servlet support
writing the html
Writing the HTML
  • Create the configuration of pages, frames, and browser windows
  • META tag or comment with proper charset
  • Use fixed text as images to solve some charset incompatibility
  • Alternate text for images may not always work
managing html forms
Managing HTML FORMs
  • FORM data is submitted in the charset of the page/frame
  • Input text and textareas are handled by the native system
  • Pre-filled text may not always look right
  • Charset conversions and defaults in browsers
slide7

More HTML quirks

  • <SELECT> and <OPTION> tags - value parameter, dynamic filling
  • Local file access and other browser-controlled elements
  • Testing environment may not work like actual environment
coding the cgi script program
Coding the CGI script/program
  • Writing internationalized CGI is like writing any internationalized programs
  • Parse FORM fields, gathering charset and locale values first
  • Code workarounds for mismatched client and server charsets, locales
  • Inspect for other data, such as HTML inside input text
test your application
Test your application
  • Set up machines in various locales as clients
  • Run server in various locales
  • Use different browsers and versions
  • Invite customers to beta test
