Developing Globalized Applications |
|
ColdFusion supplies many tags and functions that you can use to develop globalized applications. This section describes these tags and functions.
The following table shows the tags that you use most often to globalize an application:
| Tag |
Attributes |
Use |
|---|---|---|
cfprocessingdirective |
pageencoding |
Specify the encoding of a ColdFusion page so ColdFusion can parse it. For an example, see "Determining the character set of a ColdFusion page". |
cfcontent |
typeencoding |
Specify the encoding of the results returned to the client browser. For an example, see "Determining the character set of server output". |
cffile |
encoding |
Specify how to encode data written to or read from a file. For an example, see "Reading and writing file data". |
ColdFusion contains functions that you use when globalizing an application. These functions include string functions as well as date, time, currency, and numeric functions.
ColdFusion provides the following functions to process string data:
These functions recognize the Unicode encodings so they operate correctly for all single and double-byte character sets.
Note: Applications developed for previous versions of ColdFusion that assumed that the character length of a string was the same as the byte length might produce errors in ColdFusion MX.
CFML defines versions of the date, time, currency, and numeric functions that support different locales. The names of these functions are prefixed by LS. The following table lists the LS functions and several other functions used with date, time, currency, and numeric data:
You must precede calls to the LS functions with a call to the SetLocale() function in order to set the locale. If you do not, these functions default to using the locale defined by the JVM, which typically is the locale of the operating system.
The following example uses the LSDateFormat() function to display the current date in the formats for each locale supported by ColdFusion:

<p>Format the date part of a date/time value using the locale convention.
<!--- loop through a list of locales; show date values for Now()--->
