guifontwide fonts do not get larger/smaller when guifont does

[kjoonlee]

Steps to reproduce

1. Install and set different fonts for guifont and guifontwide
2. Type in English and Korean: 가나다 ABC
3. Make text larger/smaller

Actual results: only the English text gets larger/smaller; the Korean text stays the same size.

Expected behaviour

Expected results: all text would get larger/smaller

Logs and stack traces

Vim and MacVim configuration where issue is reproducable

set guifont=DejaVuSansMono:h20
set guifontwide=D2Coding:h20

Can be reproduced with different guifontwide fonts; one easy-to-get monospaced Korean font is D2Coding-Ver1.3.2-20180524.ttc from https://github.com/naver/d2codingfont/releases/tag/VER1.3.2

How was MacVim launched?

• by launching MacVim.app in macOS (by using the Dock, Spotlight, or the open command)
• by running mvim/gvim in the terminal

Issue has been tested with clean configuration

• by running mvim --clean (or gvim, supplied by MacVim distribution). You can also use the File → "New Clean Window" menu item within MacVim.
• by running vim --clean (in terminal, supplied by MacVim distribution)
• by running vim --clean (in terminal, other suppliers, e.g. /usr/bin/vim)

Ah, this is mentioned in the source:

macvim/src/MacVim/MMCoreTextView.m

Lines 1356 to 1358 in 78e8ec8

	// We don't update guifontwide for now, as panel font selection
	// shouldn't affect them. This does mean Cmd +/- does not work for
	// them for now.

I ended up writing a workaround function:

function! ResizeGuifontWide()
    let g:guifontsize=substitute(&guifont, '^.*:', '', '')
    let g:guifontwidename=substitute(&guifontwide, ':.*', '', '')
    let &guifontwide= g:guifontwidename .. ':' .. g:guifontsize
endfunction

And I call it on <C-L>:

nnoremap <C-L> :redraw!<CR>:nohls<CR>:call ResizeGuifontWide()<CR><C-L>

Hmm, we should really make it work. This feature should be intuitive.

Regardless, I actually kind of hate guifontwide to be honest. Can I ask why you use it? My hope is to deprecate the use of guifontwide in the future and just give you the ability to specify multiple fonts in guifont itself (been working on it on and off for a while).

I write bilingual text in Korean and English, and it’s difficult to find a Korean monospaced font that has English letter shapes that I like. (And there aren't that many Korean monospaced fonts, so that doesn't help.)

So I want to take Korean letter shapes from a Korean font and English letter shapes from an English font and combine those two.
