unicode

Overview ¶

Package unicode provides an alternative to the SQLite ICU extension.

Like the ICU extension, it provides Unicode aware:

• upper() and lower() functions
• LIKE and REGEXP operators
• collation sequences

Like PostgreSQL, it also provides:

• initcap()
• casefold()
• normalize()
• unaccent()

The implementations are not 100% compatible:

• upper(), lower(), initcap() casefold() use strings.ToUpper, strings.ToLower, strings.Title and cases
• normalize(), unaccent() use transform and unicode.Mn
• the LIKE operator follows strings.EqualFold rules
• the REGEXP operator uses Go regexp/syntax
• collation sequences use collate

Expect subtle differences (e.g.) in the handling of Turkish case folding.
