[SOLVED]Extra space with some font in SynEdit

[mercury]

See the screenshot.
Any idea?

This font is probably not monospaced.

SynEdit only supports monospace. for proportional fonts SynEdit finds the widest char (from a selection that it tests) and forces all others to be same as wide.

"widest char" actually is widest half width char. (even mono space has 2 widths). Chinese are full width, they always are twice as wide as latin.

The widest char in many fonts is the "@"

You can set "extra char spacing" to a negative value. But then some char will overlap.
You should find a monospaced font. "Deja vue mono" usually works well. (And if you have eastern font support installed it will fall back for Chinese to some font supporting them)

Check that you are using a recent version of Lazarus. IIRC pre-release 1.4 had this problem on my system with Linux Mint 17.

Yes I use Lazarus 1.6.

Microsoft YaHei UI is the default font in windows Chinese version. And it’s not monospaced.
I want use SynEdit for display some code in my program.
In Linux the most used default Chinese font Wen Quan Yi Zen Hei (文泉驿正黑) is display well. But I don’t want include this font in my program.
Could you suggest some Chinese font that SynEdit support (no extra space), and it’s already include in windows (no install need).

PS:
Is that possible let SynEdit support font is not monospaced?

Thank you very much.

I use SynEdit with fonts as "deja vu mono", and "courier new" both installed by default. And Chinese is displayed (ignoring that I can't read it, it looks correct) (using Win Vista)

They may not include Chinese themself, but windows uses a fallback in cases like that, and it displays the correct glyphs. (I do not know any way to control what is used a fallback)

However IIRC if a PC (like mine) was sold in Europe, then one needs to install "support for East Asian characters". Otherwise there may be no fonts for Chinese.
I cant test what happens without that support, as I already installed it.

Also depending on your locale settings, some graphic glyphs (like stars etc) may be either full or half width.

I haven't tested much on Linux. So can't advice for that.

PS:

It's a big task to implement. Maybe someday.

I didn’t see any font called ”deja vu mono” in my system(windows 8.1 and some font installed with office 2013). I will use ”Courier New”. And Chinese character display well. Behavior much like TMemo but with lots of cool features.
If someone doesn’t have any Chinese font in system, then I think that is not my program’s problem. And probably they will never want to display any Chinese character in my program.
