Allow usage specify unicode code for each character

[edouard-lopez]

I'm building a font from SVG files. For instance:

中.svg
山.svg
火.svg
西.svg
…

However 中 is associate with U+EA02 instead of U+4E2D CJK UNIFIED IDEOGRAPH-4E2D.

Question

Is there a convention I'm missing to assign a glyph to the correct codepoint?

@edouard-lopez thanks for feedback, i don't know why it is happens, need investigation, if you have time feel free to PR or create issue to related project 👍

[edouard-lopez]

@evilebottnawi I used neither startunicode nor prependUnicode argument and name the SVG file with the character (not it's codepoint).

[alexander-akait]

@edouard-lopez can you upload here one of svg?

[edouard-lopez]

Here is 中.svg and the script to build those files.

@edouard-lopez oh sorry, I did not immediately understand what you specifically mean 😄 Filename of svg files not associated with real unicode characters (). Starting unicode https://github.com/nfroidure/svgicons2svgfont/blob/master/src/metadata.js#L17 Why you need associated real filename and unicode?

[edouard-lopez]

I generate the file from Unicode database, should I use the codepoint (e.g. U+3400)?

[alexander-akait]

@edouard-lopez we can generate custom font and use the offset to not intersect with the real characters of the fonts. This approach is used by all font generators, if you can explain in more detail why you need it and for what, then maybe I can help

[edouard-lopez]

@evilebottnawi my goal is to generate a Chinese font based on Noto CJK (Chinese/Japenese/Korean) to add the pronunciation on top of each Chinese character, see repo, like example below.

But the generated glyph should have the same codepoint as the original one otherwise it will be pointless as users won't be able to type the character.

@edouard-lopez Thanks for the explanation, I think it's workable, I'll try to find a solution this week, but you can try it yourself and send PR 👍

[edouard-lopez]

I would expect an option --detect-codepoint based on the filename: either U+3400.svg or 㐀.svg.

What do you think?

[alexander-akait]

@edouard-lopez sgtm for me!

[edouard-lopez]

@evilebottnawi svgicons2svgfont already support what I wanted through a naming convention:

${unicode}-${char.glyph}.svg

For example:

└── svg
    ├── u3400-㐀.svg
    ├── u3401-㐁.svg
    ├── u3404-㐄.svg
    ├── u3405-㐅.svg
    ├── u3406-㐆.svg

@edouard-lopez it is good 😄
