ISSUE: 1944
|
|
TITLE: Increase maximum string literal length to 64K (bytes) while setting a lower
|
|
limit (of characters) for multibyte charsets based on their max char. length
|
|
(UTF-8 literals will be limited to 16383 characters)
|
|
DESCRIPTION:
|
|
Test verifies that one may to operate with string literals:
|
|
1) containing only ascii characters (and limit for this case should be 65535 bytes (=chars))
|
|
2) containing unicode characters but all of them requires 3 bytes for encoding (and limit for this should be 16383 character)
|
|
3) containing literals with mixed byte-per-character encoding requirement (limit should be also 16383 character).
|
|
Before 3.0.0.31981 following statement raises:
|
|
String literal with 65536 bytes exceeds the maximum length of 32767 bytes
