## 18.8. Internationalization & Unicode

The text being indexed and the text query expression may both be wide strings. The word boundaries used to cut the text in words in both queries and index maintenance may depend on a language declared for the text index.

The default language has white space and punctuation as word delimiters and will recognize Unicode ideographic characters as self standing. A single non-ideographic character will always be considered noise and not indexed.

Non-ASCII Unicode values are converted to UTF8 before being stored into the word table as narrow strings. Narrow 8 bit strings are stored in the words table as is.
