аа, так ты хочешь саму подробную версию истории?
вот ответ автора моего терминала:
tl;dr: your font is not a fixed-width font, which is needed for terminal
usage.

first of all, the gentoo package of urxvt comes with custom patches that
are known to be buggy and _directly affect your problem_ by altering font
widths, so it's best to use an official release, or use a gentoo-specific
support forum, when you use the gentoo package.
however, what you describe is a relatively common issue:

Looking at that, it seems that the U+2699 char is somehow between "-"
and "s" in the line above it, and that hints at the basic problem: you
need a fixed-width font (or, specifically, a cell-space font), but got a
proportional font instead.
terminals use a grid system, for example, 80x24 cells. in urxvt,
characters can be one or two cells wide (as per your locale), and all
the characters you are writing about are one cell wide in your locale.
however, looking at the above screenshot, it's quite clear that these
characters are too wide.
unfortunately, while x11 core fonts support this,
xft/fontconfig/freetype/etc. have more or less completely removed support
for internationalised terminal fonts, and there is effectively no support
for fixed-width or monospace fonts either: monospace, in xft, typically
means that ascii characters are fixed-width, and maybe some other letters,
but that's it. xft has no support for locales either, which is partially
mitigates by the fact that many fonts follow the unicode widths, and most
operating systems have compatible widths when using a utf-8 locale.
urxvt can cope with slightly wider characters up to a point, but it looks
as if some of your characters are simply too wide to fit. urxvt also does
a few guesses to see if a font has compatible widths, but it cannot check
all characters of a font (that would be way too slow), and to make things
worse, xft often delivers wrong font metrics before a character has been
rendered (i.e. when rendering a character it might suddenly be a pixel
wider than the font metrics originally claimed. since this is only detected
at rendering time, it is too late for urxvt to reconsider the font.
what you would need is a monospace fopnt where these characters really
are as wide as the letter characters (or double-wide, depending on your
locale). failing that, you can also experiment by simply chosing a smaller
font size for your powerline font, or maybe synthesizing a condensed
version of it using a transformation matrix.
