Change default char to monospaced arrow

[sunknudsen]

Description

SPACESHIP_CHAR_SYMBOL was set to "Heavy Round-Tipped Rightwards" unicode U+279C character which broke monospacing. Replaced "Heavy Round-Tipped Rightwards" character by "Rightwards Arrow".

I think it was a conscious choice by @denysdovhan

@salmanulfarzy Thanks for the follow up. I suspected the same, but found it odd that ~ and → have the same width on all official screenshots and screen captures. I followed the guidelines of https://github.com/denysdovhan/spaceship-prompt/blob/master/docs/Troubleshooting.md#why-doesnt-my-prompt-look-like-the-preview. If the current arrow is the expected one, feel free to discard this PR. Thanks for the awesome zsh prompt btw!

Even though it's not monospace and I like the rounded arrow. Anyway I'll leave the decision on whether to switch character to @denysdovhan.

[denysdovhan]

Rounded arrow just didn't look so sharp for me. However, if this causes real problems with displaying it correctly with monospaced fonts, then we may change it.

@denysdovhan On my MacBook Pro Retina (macOS Mojave), the only way I could achieve the look on https://github.com/denysdovhan/spaceship-prompt (monospaced tilde and arrow) was to set SPACESHIP_CHAR_SYMBOL="→ ". The default arrow didn’t play well with Fira Code on iTerm2. Anyhow, obviously a cosmetic "improvement". Have an amazing day!

[denysdovhan]

@sunknudsen yeah, you're right. I use fira code and iterm and have the same issue. I didn't pay attention to it earlier.
