@bencaradocdavies you provide lots of information about your font setup, but nothing about your Geany version, GTK version etc so can't help you.

Also what did you set line_height to, my crystal ball has gone hazy, it must have COVIDS?

And just for the record with the default setup DejaVu Sans Mono Book 12 works just fine on my Linux Mint with line_height `0;0;` (ie default) on Geany 1.37 (git >= 82590af4), en_AU.UTF-8 GTK 3.22.30, GLib 2.56.4.

Thanks @codebrainz, I have updated my comment above with my geany, gtk, and glib details for the record, but I just got the `line_height` workaround to work with excellent results.

For the benefit of other users, the `line_height` setting can be found in "Tools" > "Configuration Files" > "filetypes.common". To change this setting from its default `line_height=0;0;` there are two things to note:

* "#~" lines are commented and have no effect. * The file format is an [INI file](https://en.wikipedia.org/wiki/INI_file) so uncommenting the `line_height` line is insufficient because the `[styling]` section is also required; either uncomment this line or add a new `[styling]` section at the end.

The only uncommented lines in my `filetypes.common` are now:

``` [styling] line_height=0;2; ```

With this setting and DejaVu Sans Mono Book size 12, underscores are visible. Using "line_height=0;1;" also works, but "line_height=0;2;" gives me, for the first time ever, exact agreement (as far as I can tell) with the line height in xfce4-terminal.

Sigh. Apologies for the spam, but, given the number of users, myself included, unable to implement the documented fix, I thought circulating this recipe might do more good than harm. Thanks for your patience! And for geany, of course. :-)

Who knew i would comment on Crotter inc. property in this lifetim

Well, `ctrl +` (font size change) is the way I do it till those appear

i was trying all kinds of colorschemes and the underscores seem to appear in encapsed strings and remarks in geany (for what i use it on linux mint 20 ) so i tried your suggestion here and it seems from zoom-zero the underscore appears after clickinc ctrl-+ respectively , 3, 6 , 10 , 13 and up times in intervals, the zoomlevels in between dont display it . I know these sites tend to have endless discussions on how to phrase questions and what not instead of providing solutions but if the issue is not geany but appears in geany and so far (as far as i can see) nowere else in whatever i use in linux mint i would dare be so bold and preposterous as to say maybe team geany could work around this instead of shoving the blame like good politicians would (i assume this answer will be flagged and censored for 'irrelevant' and what not as if this were stackoverlords) ... but putting the font in elefants sizes does work ... at certain intervals , fyi

No it's not fixed.

Any update on this issue?

Works by increasing the default font size to 16 **and** making `#~ line_height=0;2;` in Tools > Configuration Files > filetypes.common

can confirm this works. It would still show underscore up to size 12, anything less than that the underscore would be invisible.

There has been a change to upstream Scintilla which should improve this, should be in next release.

Thanks for the workaround. I can confirm it works. This is December, 2021, just installed Debian 11 which ships with Geany 1.37.1 which has the "bug". Using `line_height=0;1;` + uncommenting [styling], works fine for me. Display was quite troublesome without being able to see underscores. Thanks again.

Note there is a fix which should improve the situation which will be available in whichever the version after 1.38 is (1.39/2.0).

Another excellent code font is [Hack](https://sourcefoundry.org/hack/) (GitHub: [source-foundry/Hack](https://github.com/source-foundry/Hack)), which has its roots in DejaVu Sans Mono / Bitstream Vera Sans Mono.

Hack has a higher underscore position and so may not be affected by this geany bug.

I have released [HackSlash](https://github.com/ashjoubert/HackSlash), a variant of the Hack typeface with forward slashed zero alternate glyphs from the [alt-hack](https://github.com/source-foundry/alt-hack) library of alternative glyphs for Hack.

[Hack](https://sourcefoundry.org/hack/) has a higher underscore position and so may not be affected by this geany bug.

Thanks @ashjoubert that did the trick.

Here's a quick easy guide:

`sudo apt install fonts-hack-ttf` Open Geany. ``` Edit > Preferences > Interface Fonts, Editor, "Hack Regular" Apply, OK. ```

if you decide to stay at an older ver.of geany

@xzhh it's not "if you" it's what the distribution ships as stable from there repos. For things like this it highlights that model is flawed but unfortunately that's how it is (if you stick with stock standard stuff for security support).
