Hi all, I'm new to i18n and to text rendering so please bear with me if I'm asking something odd or obvious.
After shaping a run of text with harfbuzz, you can get a codepoint (font glyph index) and cluster back for each glyph that remains. I want to use said cluster info to help me do line breaking later on... but when the font doesn't have the codepoint in question (or any other condition that causes harfbuzz to set hb_glyph_info_t.codepoint = 0 occurs), the cluster value is invalid as well. For example, the post shaping clusters for the following text when a Korean language font isn't present: input: "안녕하세요" clusters: 32767,32767,32767,32767,32767 Is it possible to figure out which cluster the missing glyph belonged to (aside from the example case which is obvious)? My use case is implementing a custom 'missing glyph' bitmap that isn't tied a single font for redundancy, so I need reverse lookup even when harfbuzz doesn't shape a glyph.
