(U+0021 EXCLAMATION MARK is often offset by a space in Thai.) I know it works in ICU Version 53; I haven't tested later versions. Although NBSP is available in Windows-874 and IANA-registered tis620 (as 0xA0), it is not available in TIS-620, the national 8-bit standard. What of a word break between a letter and MAIYAMOK in text tagged as Thai? Should it be never, always or sometimes? Should it depend on whether there is an intermediate space? Richard.
