cl.global.1 Enhancements to Localization Display and Line Breaking in Globalization and Runtime APIs

Access Level

Public

Reason for Change

The ICU version has been upgraded from 72.1 to 74.2. Based on the ICU 74.2 data, this update improves localization conventions, making the behavior of certain globalization and runtime APIs better aligned with regional language usage. It also enhances the system's text line-breaking capabilities.

Change Impact

This change requires application adaptation.

For detailed API behavior changes, see Affected APIs/Components. Updates to system line-breaking behavior are as follows:

Before	After
CJK ideographs did not include characters in the range U+2EBF0 to U+2EE5F.	622 ideographs and 5 special ideographic characters in this range are now included in CJK ideographs.
Line breaking between orthographic syllables was not supported for Burmese, Thai, Lao, and Khmer. For example, in a Text component, the Burmese text "သော့line-breaking pointခလောက်" would break at "line-breaking point".	Line breaking between orthographic syllables is now supported for Burmese, Thai, Lao, and Khmer. For example, in a Text component, the Burmese text "line-breaking pointသော့ခလောက်" breaks at "line-breaking point".
