1657647 - Support reading/writing utf-8 text files with IOUtils

Status: RESOLVED FIXED

(Toolkit Graveyard :: OS.File, task)

Description

[Keefer Rourke]

OS.File read and writeAtomic methods can optionally return/accept strings instead of byte arrays if the encoding option is passed. See options for writeAtomic for more detail.

The vast majority of cases where the encoding option is used, it is called with encoding: 'utf-8'.

IOUtils should support these use cases with two new methods:

1. Promise<unsigned long long> writeAtomicUTF8(DOMString path, DOMString data, ...)
2. Promise<DOMString> readUTF8(DOMString path)

This change introduces two new methods to the IOUtils interface:

1. readUTF8 will read an entire file as an UTF-8 encoded text
2. writeAtomicUTF8 will encode a provided DOMString to UTF-8 and write it
   to file
