Patch 7.4.292
|
|
|
3ef2ca |
Problem: Searching for "a" does not match accented "a" with new regexp
|
|
|
3ef2ca |
engine, does match with old engine. (David Bürgin)
|
|
|
3ef2ca |
"ca" does not match "ca" with accented "a" with either engine.
|
|
|
3ef2ca |
Solution: Change the old engine, check for following composing character
|
|
|
3ef2ca |
also for single-byte patterns.
