[Tex/LaTex] Yen (¥) symbol for backslash (\) in TexWorks

texworks

Hi I am running TexWorks 0.6.2 on windows 10. In my text editor ( of texworks) whenever I type backslash (\) it is replaced by yen symbol (¥). The code compiles normally and if I copy the code and paste it on notepad or some other editor it shows (\). I was wondering if there is some setup in TexWorks which is causing this issue. I don't have this issue on command prompt or any other editor.

Since the OP's problem has been solved through the conversation in comment section, I'll post it as an answer. However, I doubt this question deserves an answer because it is more of a problem of font design than that of TeX/TeXworks and might be off-topic here. If this question should be closed and I shouldn't post an answer, feel free to let me know.

Some Japanese fonts, e.g., MS, Yu, IPA, and Meiryo, render U+005C (REVERSE SOLIDUS) as a yen symbol while yen symbol is assigned to U+00A5 and 0xA5 in Latin-1 encoding. This stems from the fact that the code point 0x5C in Shift_JIS means yen symbol. Developers of the fonts above decided to employ a yen symbol as a glyph for U+005C so that inexperienced users do not get confused with the change in the appearance of the character. Therefore, what the OP considered as a yen symbol is actually a backslash that mimics a yen symbol (ridiculous phrase but I hope you understand the meaning).

So, the solution to the problem is to use a font that renders U+005C as a backslash. Below is a list of monospaced fonts that cover Japanese characters and render U+005C as a backslash. The OP does not need a Japanese font in TeXworks, but I'd like to write down for the sake of completeness. The latter two links are unfortunately available only in Japanese.

  • Source Han Code JP: based on Source Han Sans and Source Code Pro.
  • Migu 1M: based on IPA and M+.
  • Ricty: based on Inconsolata and Migu 1M. You need to run a shell script to create Ricty due to lisence restriction.
