RegEx matching: ranges not computed correctly in "ignore case" mode
-------------------------------------------------------------------
Key: XERCESJ-1389
URL: https://issues.apache.org/jira/browse/XERCESJ-1389
Project: Xerces2-J
Issue Type: Bug
Components: Other
Affects Versions: 2.9.1
Reporter: Radu Preotiuc-Pietro
There are a couple of problems in interpreting character ranges in
"case-insensitive" mode.
When doing range subtraction (or negation), all the case-variants of the
subtracted characters need to be considered. For example, "[^Q]" means, in
case-insensitive mode, "any character except 'q' or 'Q'" but the regex engine
matches both 'q' and 'Q' in this example.
Also, in case-insensitive mode, all character classes must stay the same, so
for example "\p{Lu}" would not match a lowercase letter, but the regex engine
matches 'q'.
