I wanted to center a tall integral on the screen an another funky character pleasantly surprised me

First I used LF

[root@kindle us]# fbink -t regular=/mnt/us/linkfonts/fonts/Symbola_Hinted.ttf,size=72 -M -m -c "⌠
> ⎮
> ⌡"  #Tall integral with line feeds U+0A
[FBInk] Enabled Legacy einkfb Kindle quirks
[FBInk] Clock tick frequency appears to be 100 Hz
[FBInk] Screen density set to 167 dpi
[FBInk] Variable fb info: 600x800, 4bpp @ rotation: 0 (Upright, 0°)
[FBInk] Fontsize set to 16x16 (IBM base glyph size: 8x8)
[FBInk] Line length: 37 cols, Page size: 50 rows
[FBInk] Fixed fb info: ID is "eink_fb", length of fb mem: 483328 bytes & line length: 300 bytes
[FBInk] Pen colors set to #000000 -> #FFFFFF for the foreground and #FFFFFF -> #000000 for the background
Loading font '/mnt/us/linkfonts/fonts/Symbola_Hinted.ttf' for the Regular style
[FBInk] Font '/mnt/us/linkfonts/fonts/Symbola_Hinted.ttf' loaded
Printing string '⌠
⎮
⌡' @ 72pt, honoring the following margins { Top: 0px, Bottom: 0px, Left: 0px, Right: 0px } (formatted: N, overlay: N, no BG: N, no FG: N, inverted: N, flashing: N, centered: Y, H align: 0, halfway: Y, V align: 0, clear screen: Y, skip refresh: N)
[root@kindle us]# ./screenshot
 is centered and halfway as expected

Then I used LS, and was surprised that it also worked!

[root@kindle us]# fbink -t regular=/mnt/us/linkfonts/fonts/Symbola_Hinted.ttf,size=72 -M -m -c "⌠

 remarkably, is also centered and halfway
