ICU (International Components for Unicode) is a set of libraries providing globalization support for the internationalization of software systems.
Translations with ICU message format syntax are supported.
If the option to
is available for the file format and selected, the messages are parsed and presented in the CAT editors.-
To ensure that the files with ICU messages are properly exported after the translation is finished, tags in the target segment need to correspond to those in the source segment and tags in the source segment should not be edited.
-
As result of new parsing, it may be necessary to move some parts of texts from one target segment to a different target segment so that translations corresponding to grammatical rules of the target languages are followed. To view the translated ICU messages in their entirety, consult the in-context preview.
-
Segments representing particular forms (sub-messages) are saved in the translation memory and are leveraged in the translation process.
Supported file types:
-
.XLIFF 1.2
-
.XLIFF 2.0
-
.SDL XLIFF
-
.JSON
-
.XML
-
Multilingual .XML
-
.PO
-
.YAML
-
Android Strings
-
iOS Strings
If ICU messages are present when a file is imported as a job and segmented, the segment is labelled as in the CAT editors with the ICU type presented in the left hand column. The ICU content is presented as a tag within the text.
Hovering over the ICU type displays categories and an example of usage in a tooltip.

All information regarding the ICU message is imported and viewable as a context note with the full form of the message presented in the in-context preview.
ICU messages cannot be split or joined.
Repetitions
ICU primary messages and sub-messages, if they are repeated in a job and have the same key, are identified as repetitions.
QA
To avoid false positives (generating QA warnings for inconsistent translations where such warning is not wanted) and false negatives (no QA warnings for translations where such warning is wanted), ICU context is considered.
In case of different context:
-
The
is not displayed in the case of different translations. -
The
is displayed for ICU messages with the identical translation and the same source text but with a different context key.
