Subject: 26.1; Emacs performance strike when using source-code-pro and unicodes together
--text follows this line--
Hello,
Explanation:
emacs is extremly slow on my windows 10 when using the Source-Code-Pro-Font
unicode-characters (tested with two examples θ and μ).
I set the font by following lisp code in my init.el file:
"(set-frame-font "-outline-Source Code Pro-normal-normal-normal-mono-*-*-*-*-c-*-windows-1258")"
Question:
On which side lies the error? On Emacs, on the Font, on Windows (as usual), or something between my chair and my keyboard(also, as usual)?
Reproduction:
- Install source-code-pro on your windows 10
- Open Emacs
- Switch buffer to: *scratch*
- ;;After setting the font. Copy&paste&execute the cmds step by step. As soon as the unicode (θ) is displayed in emacs, emacs will begin to proceed slowly after the font is set.
- (set-frame-font "-outline-Source Code Pro-normal-normal-normal-mono-*-*-*-*-c-*-windows-1258")
- (insert "a") ;; inserts fast
- (insert "θ") ;; inserts slow, why?
Profiler-Report:
I created two reports with the profiler. One with the font "Alef" (just
a random font where the problem don't occur.)
And one with the Source-Code-Pro-Font. I just saw that with source code pro there are more bytes needed. Can you tell me more?
