Internationalization

IG supports internationalization (i18n) to facilitate localization for target audiences that vary in culture, region, or language.

Information type Character set/encoding

Information type	Character set/encoding
HTTP header names and values	US-ASCII
HTTP trailer names and values	US-ASCII
Response entities for StaticResponseHandler	The `Content-Type` header must be set. For text content, the character set must also be specified; for example: `Content-Type: text/html; charset=utf-8` `Content-Type: text/plain; charset=utf-8` The entity must conform to the content type.
Text in request and response entities for CaptureDecorator	If the `Content-Type` header is set for the request or response, the decorator uses it to decode the text in request or response messages, and then writes them to the logs. If the `Content-Type` header is not set, the decorator does not write the request or response messages to the logs.
Logs	The system default character set where IG is running. To use a different character set, configure `logback.xml` as described in Change the character set and format of log messages.
IG configuration files	UTF-8
Hostnames	US-ASCII Non US-ASCII characters must be escaped with Punycode encoding.
URIs	US-ASCII Non US-ASCII and reserved characters must be escaped with percent-encoding.
