Description (English):

ISO/IEC 9995 defines a framework for the layout of all alphanumeric and numeric keyboards across the widest spectrum of today's and upcoming applications using keyboards. The functions to be performed by keyboards are grouped into three categories that correspond to the main physical sections of the keyboard. Application of ISO/IEC 9995 in the design of keyboards will provide the user with a unified, predictable user-machine interface by dividing the keyboard into functional areas and sections and allocating functions to keys. ISO/IEC 9995-10:2013 describes conventional symbols and methods to represent graphic characters not uniquely recognizable by their glyph on keyboards and in documentation.

Abstract

Overview

ISO/IEC 9995-10:2013 is Part 10 of the ISO/IEC 9995 series on keyboard layouts for text and office systems. It defines conventional symbols and methods to represent graphic characters that cannot be uniquely recognized by their glyph on keyboards and in documentation. The document standardizes how ambiguous or similar-looking characters (for example, variants of dashes, commas, diacritics, slashes, less/greater-than signs) are indicated so users and implementers have a clear, language-neutral representation.

Key topics and technical requirements

Scope and purpose: Provides a set of universal symbols to distinguish characters that share the same or similar glyphs when the glyph itself is ambiguous or misleading in documentation or on keys.
Symbol inventory: Defines symbol groups covering practical problem areas - e.g., universal dash forms, tilde variants, asterisk, full stop/period, comma variants, less/greater-than and much-less/much-greater-than, free-standing acute/grave accents, slash variants, diacritical marks and modifier letters. (Symbols are enumerated in the standard; combinations and special cases are included.)
Diacritic handling: Includes symbols for diacritical marks (symbols 41–44) that generically represent the base character a diacritic applies to; distinguishes whether a diacritic is typed before or after the base character and prescribes centering rules when a diacritic spans two base letters for left‑to‑right vs right‑to‑left scripts.
Modifier letters and special combinations: Provides separate symbols for modifier letters (symbol 45) and special combinations (symbols 46–50) where using the generic mark would be problematic.
Graphic augmentation: For other lookalike characters, the standard prescribes augmented symbols (small dot, short line, or special mark) to disambiguate them.
Conformance and presentation: Equipment or documentation conforms if it meets Clause 5. Symbols must be reproduced in the orientation shown in Table 1 and cited as “ISO 9995-10-xxx” when referenced elsewhere. Names are given in English and French; descriptions in the table are informative.

Practical applications - who uses this standard

Keyboard designers and manufacturers: to label keys unambiguously for multilingual and specialized keyboards.
Operating system and firmware developers: to map and display keyboard legends consistently.
Localization and internationalization engineers: to document input behavior where glyphs are ambiguous across scripts.
Technical writers, standards bodies, and typographers: to produce clear documentation, user guides, and specification sheets.
Accessibility and UI designers: to reduce input errors by clarifying visually similar characters.
