Martin Atkins	d2d1b52f43	lang/langserver: Helpers for converting source positions ... LSP and HCL use different representations of source positions, so we need to be able to convert back and forth while translating incoming requests to the HCL API and HCL API responses into LSP responses. Such conversions cannot be exact in the LSP->HCL direction because HCL column positions are at a lower granularity (grapheme clusters) than LSP column positions (UTF-16 code units), and even at the individual codepoint level UTF-16 code units and codepoints cannot be converted one-to-one in the presence of UTF-16 surrogate pairs. Therefore these conversions are for "cosmetic" purposes and should not be used for incoming text editing requests or else our local buffer may get out of sync with the one in the client.	6 years ago
