I wanted to make a code highlighting plugin in Notepad ++ in real time using regular expressions. Initially, when regular expressions were inside the code, it worked well. When I moved the settings to the ini-file, the highlighting began to occur slowly. For fun, I made an option using PureBasic Internal Regular Expressions (PCRE), because the regular expressions in Scintilla were stripped down. But in some places the highlighting was performed with a shift (to the end of the text) and I found that this happens at the moment the Russian symbols appear.
Here's an example where it worked fast enough. yandex upload.ee
