Original GitHub issue: https://github.com/documenso/documenso/issues/1333

Issue Description

Special unicode characters like currency symbols in fillable form fieldsis causing an error in the Api

Steps to Reproduce

Include special unicode characters in formValues of the generate-document api. If the unicode characters are removed, it works just fine.

Expected Behavior

When typed manually the pdf accepts those characters and the template should accept that while generating the document

Current Behavior

{ _err: Error: WinAnsi cannot encode "₹" (0x20b9) at Encoding.encodeUnicodeCodePoint (/app/node_modules/@pdf-lib/standard-fonts/lib/Encoding.js:23:23) at StandardFontEmbedder.encodeTextAsGlyphs (/app/node_modules/pdf-lib/cjs/core/embedders/StandardFontEmbedder.js:88:41) at StandardFontEmbedder.encodeText (/app/node_modules/pdf-lib/cjs/core/embedders/StandardFontEmbedder.js:28:27) at PDFFont.encodeText (/app/node_modules/pdf-lib/cjs/api/PDFFont.js:37:30) at exports.layoutSinglelineText (/app/node_modules/pdf-lib/cjs/api/text/layout.js:197:24) at exports.defaultTextFieldAppearanceProvider (/app/node_modules/pdf-lib/cjs/api/form/appearances.js:260:31) at PDFTextField.updateWidgetAppearance (/app/node_modules/pdf-lib/cjs/api/form/PDFTextField.js:719:61) at PDFTextField.updateAppearances (/app/node_modules/pdf-lib/cjs/api/form/PDFTextField.js:713:18) at PDFTextField.defaultUpdateAppearances (/app/node_modules/pdf-lib/cjs/api/form/PDFTextField.js:689:14) at PDFForm.updateFieldAppearances (/app/node_modules/pdf-lib/cjs/api/form/PDFForm.js:542:23) }
